Product details
Overview
NCP600SN300T1G from onsemi is a fixed-output 3.0 V, 150 mA low-dropout (LDO) linear regulator in TSOP-5 package, featuring 150 mV dropout at full load, ±2% output voltage tolerance over −40 °C to +125 °C, and 50 µVrms output noise - designed for noise-sensitive portable battery-powered systems including RF front-ends and camera modules.
For engineers reviewing the NCP600SN300T1G datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed 3.0 V output accuracy under load/temperature variation, fast 15 µs enable turn-on time, thermal shutdown at 175 °C, and compatibility with low-ESR ceramic capacitors without stability compensation.
Technical Context
The NCP600SN300T1G implements a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR (62 dB @ 120 Hz). It integrates internal current limiting, thermal shutdown with 10 °C hysteresis, and logic-level enable control with 0.9 V high-threshold and 0.4 V low-threshold.
As a fixed-voltage variant, it uses the ADJ pin as no-connect (NC), eliminating external resistor networks. Its ground current remains stable at 140 µA typical across 1–150 mA load, supporting low-power standby operation in handheld instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over −40 °C to +125 °C and 1–150 mA load - ensures stable core voltage for microcontrollers and sensors without trimming. |
| Dropout Voltage | 75 mV max at 150 mA - enables regulation from 3.075 V input, critical for single-cell Li-ion or Li-poly battery applications down to end-of-discharge. |
| PSRR | 62 dB @ 120 Hz - suppresses switching noise from upstream DC-DC converters in SMPS post-regulation architectures. |
| Output Noise | 50 µVrms (10 Hz–100 kHz) - meets stringent requirements of VCOs, RF receivers, and precision ADC reference supplies. |
| Enable Threshold | VTH(HI) = 0.9 V, VTH(LO) = 0.4 V - compatible with 1.8 V/3.3 V GPIOs and supports direct connection to VIN when enable function is unused. |
| Thermal Shutdown | Activates at 175 °C with 10 °C hysteresis - protects against sustained overload or poor PCB thermal design in compact enclosures. |
| Ground Current | 140 µA typical at 150 mA load - minimizes quiescent power loss in always-on subsystems like real-time clocks or sensor wake-up circuits. |
Pinout & Package
Package: TSOP-5 (Case 483), 3.00 × 1.50 × 0.95 mm, Pb-free, moisture sensitivity level MSL1/260.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Positive power supply input | Accepts 1.75 V to 6.0 V; must be decoupled with ≥1.0 µF ceramic capacitor placed adjacent to pin for transient immunity. |
| 2 - GND | Power supply ground | Device substrate connection; requires low-impedance PCB ground plane tie to minimize noise coupling and thermal resistance. |
| 3 - ENABLE | Logic-controlled enable input | Pull ≤0.4 V to disable (IDIS ≤1.0 µA); pull ≥0.9 V to enable; connect directly to VIN if unused to ensure always-on operation. |
| 4 - VOUT | Regulated 3.0 V output | Delivers up to 150 mA; requires ≥1.0 µF output capacitor; stable with zero-ESR ceramic types; overshoot clamp limits transient spikes to +20 mV. |
| 5 - ADJ/NC | No-connect (fixed-voltage version) | Not internally connected; may be left floating or tied to GND/VOUT per layout convenience; no routing required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 75 mV max at 150 mA enables operation from near-dead batteries - extends runtime in portable medical and IoT edge devices. |
| Low-noise regulation | 50 µVrms noise without bypass capacitor eliminates need for secondary filtering - reduces BOM count and board area in RF signal chains. |
| Fast enable response | 15 µs turn-on time supports dynamic power sequencing in multi-rail systems - avoids brown-out during processor wake-up events. |
| Thermal protection | 175 °C shutdown with 10 °C hysteresis prevents latch-up during short-circuit faults - enhances reliability in unattended industrial monitoring nodes. |
| Wide input range | 1.75 V to 6.0 V operation accommodates diverse sources including single-cell Li-ion, USB, and legacy 5 V rails - simplifies power architecture reuse. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 300 mA output, 175 mV dropout at 250 mA, 65 µVrms noise, SOT-23-5 package | Higher current capability but larger dropout and higher noise - suitable where headroom > 0.5 V exists and 300 mA peak is needed | Select when higher output current or SOT-23 footprint is preferred; verify thermal margin at 150 mA due to higher RθJA. |
| Torex XC6206P302MR-G | 150 mA output, 200 mV dropout at 150 mA, 40 µVrms noise, SOT-25 package | Lower noise but higher dropout and no enable pin - ideal for always-on, space-constrained designs without sequencing needs | Choose for ultra-low-noise priority and simplified enable-free layouts; confirm minimum input voltage (≥3.2 V) meets system battery profile. |

FAQ
What is the maximum input voltage rating for the NCP600SN300T1G?
The NCP600SN300T1G has an absolute maximum input voltage of 6.5 V. Operation above 6.0 V is outside the recommended operating range and may compromise reliability or trigger overvoltage protection mechanisms not specified in the datasheet. For continuous operation, keep VIN ≤ 6.0 V with appropriate derating for thermal conditions.
Does the NCP600SN300T1G require an external capacitor on the ADJ pin?
No - the NCP600SN300T1G is a fixed-output 3.0 V variant, and the ADJ pin is internally disconnected (no-connect). It requires no external components on this pin; leaving it unconnected or tying it to GND/VOUT has no functional impact and is layout-flexible.
What is the thermal resistance (RθJA) of the NCP600SN300T1G in its TSOP-5 package?
The NCP600SN300T1G in TSOP-5 (Case 483) has a typical junction-to-ambient thermal resistance of 215 °C/W under standard test conditions (645 mm² copper area, 1 oz thickness). Actual RθJA depends on PCB layout; adding thermal vias to the GND pad significantly improves heat dissipation.
Can the NCP600SN300T1G be used with ceramic output capacitors?
Yes - the NCP600SN300T1G is explicitly designed for stability with low-ESR ceramic capacitors (≥1.0 µF). Unlike many LDOs, it imposes no minimum ESR requirement, simplifying design and reducing cost versus tantalum or aluminum electrolytic alternatives.
What is the enable turn-on time specification for the NCP600SN300T1G?
The NCP600SN300T1G has a typical output turn-on time of 15 µs when ENABLE transitions from low to high. This value is confirmed for 3.0 V output variants and remains consistent across temperature (−40 °C to +125 °C) and load (1–150 mA), enabling precise power sequencing in real-time systems.
