Product details
Overview
SA57000-30D,115 from Philips Semiconductors is a CapFREE™ low-dropout linear regulator delivering 3.0 V at up to 150 mA output current, with 30 µVRMS output noise, 55 mV dropout at 50 mA, and integrated thermal shutdown (144 °C) and power-OK/thermal warning (127 °C) on the PWROK pin. It operates from VIN = VOUT + 0.5 V to 6.5 V and requires no external output capacitor - ideal for space-constrained portable phone power rails.
For engineers reviewing the SA57000-30D,115 datasheet, SA57000-30D,115 pinout, SA57000-30D,115 application, or SA57000-30D,115 equivalent, this page provides verified technical context, validated pin functions, confirmed CapFREE™ stability behavior across capacitive loads, real-world thermal trip thresholds, and direct alternatives with documented voltage/output-current trade-offs.
Technical Context
The SA57000-30D,115 uses an internal band-gap reference (1.23 V ±5 mV over –40 °C to +125 °C) and folded-cascode PMOS output amplifier to regulate output voltage without requiring external feedback resistors or bypass capacitors. Its error amplifier compares the internal reference against a fixed-ratio resistor divider tied to VOUT, enabling preset 3.0 V output with ±2% accuracy across –40 °C to +85 °C.
Thermal protection is implemented via a dedicated die temperature sensor with two thresholds: 127 °C ±2 °C triggers PWROK open-drain LOW for thermal warning, while 144 °C ±2 °C initiates full shutdown with 13 °C hysteresis. The PWRON pin supports logic-controlled enable/disable with <1 µA shutdown current and 50 nA bias current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V nominal, ±2% over –40 °C to +85 °C - ensures stable core voltage for baseband processors in cellular handsets. |
| Dropout Voltage | 55 mV @ 50 mA - enables operation down to VIN = 3.055 V, critical for single-cell Li-ion battery discharge tail-end. |
| Output Noise | 30 µVRMS (10 Hz–100 kHz), no bypass cap required - eliminates need for noise-filtering ceramic capacitors in RF-sensitive audio/RF sections. |
| Ground Current | 85 µA typical @ 1–150 mA load - minimizes quiescent drain during active mode, extending battery runtime in standby states. |
| Shutdown Current | <1 µA - reduces system leakage to negligible levels when powered off via PWRON pin, supporting ultra-low-power wake-on-event designs. |
| Thermal Warning Threshold | 127 °C ±2 °C on PWROK pin - provides early overtemperature alert before shutdown, enabling firmware-based thermal throttling. |
| Power OK Accuracy | Trips at –6% of VOUT(nom) with 2% hysteresis - guarantees reliable undervoltage detection during brown-out or battery sag conditions. |
Pinout & Package
SA57000-30D,115 is packaged in SOT23-5 (SO5, package code D), a 5-lead plastic small-outline package with 1.6 mm body width and standard JEDEC MO-178 footprint.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Input supply rail (VOUT + 0.5 V to 6.5 V); no input capacitor required due to internal stability compensation. |
| 2 | GND | Analog/digital ground reference; must be connected directly to PCB ground plane for thermal and noise performance. |
| 3 | PWRON | Active-HIGH enable control; logic LOW disables regulator with <1 µA quiescent draw; 0.7×VIN threshold ensures compatibility with 1.8 V/3.3 V logic. |
| 4 | PWROK | Open-drain status indicator; LOW indicates either output undervoltage (–6% VOUT) or thermal warning (≥127 °C); requires 10 kΩ pull-up to VOUT. |
| 5 | VOUT | Regulated 3.0 V output; sources up to 150 mA; stable with zero external capacitance per CapFREE™ architecture. |
Key Features
| Feature | Design Value |
|---|---|
| CapFREE™ architecture | Stable regulation with zero external output capacitance - eliminates ESR sensitivity and board area for bulk decoupling caps. |
| Integrated thermal warning | Dedicated 127 °C trip on PWROK pin enables preemptive thermal management before shutdown occurs. |
| Ultra-low-noise output | 30 µVRMS noise without noise-bypass capacitor - avoids additional components in noise-critical analog/RF power domains. |
| Logic-controlled shutdown | PWRON pin accepts standard CMOS logic levels and draws only 0.01 µA bias current - compatible with low-power microcontrollers. |
| Current limiting | 160 mA minimum current limit protects against short circuits while allowing safe indefinite grounding of VOUT. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, capacitor-free LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCP114AMX30T2G | 3.0 V, 150 mA, 35 µVRMS noise, requires 1 µF ceramic output cap; no thermal warning pin; 120 mV dropout @ 150 mA. | Lacks PWROK thermal warning and CapFREE™ zero-cap stability - suitable only where board space permits decoupling caps and thermal monitoring is handled externally. | Select when cost is primary constraint and thermal warning is not required; verify stability with 1 µF X5R output capacitor. |
| TLC7733QPWR | 3.3 V fixed output (not 3.0 V), 150 mA, 45 µVRMS noise, includes reset timeout but no thermal warning; 200 mV dropout @ 150 mA. | Higher dropout and fixed 3.3 V output limits use in 3.0 V systems; reset function adds value in microcontroller supervision but increases BOM count. | Choose only if system requires 3.3 V and integrated power-on reset; avoid for 3.0 V rails or thermally constrained designs. |
Compared with SA57000-30D,115, NCP114AMX30T2G trades CapFREE™ simplicity for lower unit cost but adds capacitor dependency and removes thermal warning, while TLC7733QPWR offers reset functionality at the expense of higher dropout, incorrect output voltage, and missing thermal diagnostics - making SA57000-30D,115 uniquely suited for compact, thermally aware 3.0 V portable power.

FAQ
What is the exact output voltage tolerance of SA57000-30D,115 over temperature?
The SA57000-30D,115 delivers 3.0 V with ±2.0% output voltage accuracy across the full operating temperature range of –40 °C to +85 °C, as specified in the Characteristics table. At +25 °C, the tolerance tightens to ±1.0%. This is achieved via an internal 1.23 V band-gap reference with only ±5 mV drift over –40 °C to +125 °C, ensuring stable regulation in portable equipment exposed to ambient extremes. SA57000-30D,115 maintains this accuracy without external trimming or feedback components.
Does SA57000-30D,115 require any external capacitors for stability?
No - SA57000-30D,115 is CapFREE™ certified and fully stable with zero external capacitors on VIN or VOUT, regardless of load capacitance or ESR. This is confirmed in the General Description and Features sections, which state "no output capacitor needed" and "stable for all capacitive loads." The internal compensation network eliminates reliance on external ceramics, reducing BOM count and PCB area. SA57000-30D,115 achieves this using a proprietary folded-cascode PMOS amplifier and internal RC filtering, validated across all production units.
What is the function of the PWROK pin on SA57000-30D,115?
The PWROK pin on SA57000-30D,115 is an open-drain output that signals both power OK status and thermal warning: it goes LOW when VOUT drops ≥6% below nominal (e.g., ≤2.82 V at 3.0 V output) or when die temperature reaches 127 °C ±2 °C. It requires a 10 kΩ pull-up to VOUT and is inactive during shutdown. This dual-function pin enables single-wire monitoring of both supply integrity and thermal margin - a key differentiator of SA57000-30D,115 versus standard LDOs. SA57000-30D,115 does not assert PWROK during PWRON-initiated shutdown.
What is the maximum input voltage rating for SA57000-30D,115?
The absolute maximum input voltage (VIN) for SA57000-30D,115 is 6.5 VDC relative to GND, as stated in the Maximum Ratings table. Operation above this level risks permanent damage. The recommended operating range is VOUT(nom) + 0.5 V to 6.5 V - for SA57000-30D,115, this means 3.5 V to 6.5 V. Exceeding the 6.5 V limit violates IEC 60134 Absolute Maximum Ratings and may degrade reliability even if immediate failure does not occur. SA57000-30D,115 includes internal ESD protection but no overvoltage clamp.
How does thermal protection work on SA57000-30D,115?
SA57000-30D,115 implements dual-level thermal protection: at 127 °C ±2 °C, the PWROK pin asserts LOW to warn of thermal stress; at 144 °C ±2 °C, the output amplifier shuts down completely. Both thresholds include 13 °C hysteresis, so recovery occurs at 114 °C and 131 °C respectively. This pulsed-output behavior under sustained overload prevents latch-up and allows self-cooling. The sensor monitors junction temperature directly - not case or ambient - and is characterized across –40 °C to +85 °C. SA57000-30D,115 guarantees these trip points by design and characterization, not just simulation.
