Product details
Overview
AP7380-36W5-7 from Diodes Incorporated is a fixed-output 3.6V ultra-low dropout (ULDO) linear regulator IC designed for space-constrained portable and battery-powered systems. It delivers up to 150mA output current with 500mV dropout at 50mA, ±1% output voltage accuracy, and only 1.8–3.0µA ground current across load, enabling long battery life in USB peripherals and handheld instrumentation.
For engineers reviewing the AP7380-36W5-7 datasheet, AP7380-36W5-7 pinout, AP7380-36W5-7 application, or AP7380-36W5-7 equivalent, key selection criteria include wide 3.5–24V input range compatibility, thermal shutdown protection, low-ESR ceramic capacitor support, and SOT25 (W5) package footprint for compact PCB layouts.
Technical Context
The AP7380-36W5-7 integrates a precision voltage reference, error amplifier, resistor network for fixed 3.6V output, current-limit circuit (150mA typical), and enable control logic. Its architecture supports stable regulation under fast load transients and wide temperature variation (−40°C to +125°C).
It features thermal shutdown activation at +160°C with +20°C hysteresis, ultra-low quiescent current (≤3.0µA), and line/load regulation of ≤0.05%/V and ≤0.5%, respectively - critical for maintaining signal integrity in low-noise analog and mixed-signal subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.6V ±1% - ensures stable power rail for 3.3V-tolerant microcontrollers and sensors without external feedback. |
| Input Voltage Range | 3.5V to 24V - supports direct connection to 12V/24V industrial buses or multi-cell Li-ion packs without pre-regulation. |
| Dropout Voltage | 360–580mV @ 50mA - enables regulation down to VIN = 4.16V, preserving headroom in battery discharge cycles. |
| Ground Current | 1.8–3.0µA @ IOUT = 0–150mA - minimizes standby power loss in always-on IoT edge nodes. |
| Current Limit | 150mA typical - provides robust short-circuit protection without external current-sense components. |
| Thermal Shutdown | +160°C activation with +20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| Line Regulation | ≤0.05%/V - maintains output stability despite input ripple from switching converters or unregulated adapters. |
Pinout & Package
SOT25 (W5) package: 5-pin surface-mount outline with exposed pad (non-electrical), 3.0mm × 2.8mm footprint, 0.95mm height, and matte tin-plated leads compliant with J-STD-020 Level 1 moisture sensitivity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts 3.5–24V with internal overvoltage clamp up to 30V. |
| 2 | GND | Analog/digital ground reference; requires low-impedance PCB plane for noise immunity and thermal dissipation. |
| 3 | VOUT | Regulated 3.6V output; stable with ≥1.0µF ceramic capacitor (low-ESR compatible). |
| 4 | NC | No connect - internally floating; must be left unconnected per datasheet. |
| 5 | EN | Active-high enable input; pulls device into ultra-low standby mode (<0.01µA) when driven <0.4V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range Support | Operates from 3.5V to 24V input - eliminates need for intermediate buck stages in multi-rail systems. |
| Ultra-Low Quiescent Current | 1.8–3.0µA ground current across full load - extends battery runtime in sleep-mode sensor nodes. |
| Low-ESR Ceramic Cap Compatibility | Stable with ≥1.0µF X5R/X7R MLCCs - reduces BOM count and board area vs. tantalum or electrolytic alternatives. |
| Integrated Thermal Protection | +160°C shutdown with +20°C hysteresis - prevents latch-up and enables safe auto-recovery after fault clearance. |
| High Output Accuracy | ±1% initial tolerance over temperature - ensures reliable operation of ADC references and RF front-end biasing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3602E/TO | 3.6V fixed, 250mA, 600mV dropout @ 250mA, 2.0µA IQ, TO-92 package | Larger through-hole footprint; no enable pin; higher dropout limits low-VIN usability | Preferred for cost-sensitive, non-space-constrained designs where SMT assembly is unavailable. |
| Torex XC6206P362MR-G | 3.6V fixed, 250mA, 400mV dropout @ 100mA, 1.0µA IQ, SOT23-5 package | Smaller SOT23-5 footprint but lower thermal resistance margin; no thermal shutdown | Selected when ultra-low IQ dominates design priority and thermal derating can be managed externally. |
Compared with MCP1700-3602E/TO and XC6206P362MR-G, the AP7380-36W5-7 uniquely combines 24V input tolerance, integrated thermal shutdown, and SOT25's balanced thermal performance - making it optimal for industrial-grade portable equipment requiring robustness and compactness.

FAQ
What is the minimum input voltage required for regulation at 3.6V output?
The AP7380-36W5-7 requires a minimum input voltage of 3.5V to maintain regulation. At 50mA load, its dropout is 360–580mV, so VIN must exceed 4.16V to guarantee stable 3.6V output under worst-case conditions. Below 3.5V, the device enters undervoltage lockout and disables output.
Can the AP7380-36W5-7 operate without an enable signal connected?
Yes - the EN pin is active-high and defaults to enabled when left open or pulled high via internal bias. However, for lowest standby current (<0.01µA), EN must be actively driven below 0.4V. Leaving EN floating is acceptable but does not achieve ultra-low-IQ shutdown mode.
Is a bypass capacitor required on the VOUT pin, and what value is recommended?
Yes - a minimum 1.0µF ceramic capacitor (X5R/X7R, ≤100mΩ ESR) is required on VOUT for stability and transient response. The datasheet confirms compatibility with low-ESR MLCCs and specifies no additional series resistance needed, simplifying filtering design versus older LDOs requiring RC networks.
Does the AP7380-36W5-7 meet automotive qualification standards?
No - the AP7380-36W5-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP7380Q series) with PPAP capability and IATF 16949 manufacturing, but this standard part is intended for commercial/industrial applications only. Its operating junction temperature range (−40°C to +125°C) supports many non-automotive harsh environments.
