Product details
Overview
RAA2144044GP3#JA0 from Renesas Electronics is a 3.6V fixed-output, low-quiescent current (3.8µA) PMOS LDO regulator in a 5-pin SOT-23 package, rated for 150mA output and 40V max input voltage. It features ±3% output accuracy over line/load/temperature, enable control, UVLO with hysteresis, and thermal shutdown - deployed in battery-powered motor drives and portable instrumentation.
For engineers reviewing the RAA2144044GP3#JA0 datasheet, RAA2144044GP3#JA0 pinout, RAA2144044GP3#JA0 application, or RAA2144044GP3#JA0 equivalent, key selection criteria include dropout voltage at 100mA (495mV typ), shutdown current (<0.5µA), stability with 2.2µF ceramic output capacitor, and SOT-23 pin compatibility with EN/VIN/GND/NC/VOUT assignments.
Technical Context
The RAA2144044GP3#JA0 implements a PMOS pass transistor architecture with internal bandgap reference and error amplifier feedback loop to maintain regulated 3.6V output across load (0–150mA), input (3.9–40V), and temperature (−40°C to +125°C) variations. Its UVLO rising/falling thresholds (2.42V / 2.2V) and EN threshold (1.5V typ) provide noise-immune power sequencing.
It integrates short-circuit current limiting (250mA typ) and over-temperature shutdown (150°C trip, 20°C hysteresis), with thermal resistance θJA = 174°C/W enabling operation in compact PCB layouts without heatsinking under moderate power dissipation conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.6V ±3% - ensures stable rail for 3.3V-tolerant logic or analog sensors requiring tight regulation across full operating range. |
| Max Input Voltage | 40V - supports wide-input industrial or automotive supply rails, with 45V transient tolerance for robustness against load dump. |
| Quiescent Current | 3.8µA typ - enables multi-year battery life in always-on IoT nodes or remote sensors with infrequent wake-up cycles. |
| Dropout Voltage | 495mV typ at 100mA - allows regulation from 4.095V input, critical for maintaining output during brownout or battery discharge. |
| Output Accuracy | ±3% over line/load/temp - eliminates need for external trimming in cost-sensitive consumer and industrial applications. |
| Enable Threshold | VEN rising = 1.5V typ - compatible with 1.8V/3.3V GPIOs and resistor-divider control for programmable power sequencing. |
| Thermal Shutdown | 150°C trip with 20°C hysteresis - prevents thermal runaway during sustained overload while avoiding oscillation near limit. |
Pinout & Package
RAA2144044GP3#JA0 is housed in a 5-lead SOT-23 package (JEDEC MO-178AA), with exposed pad for thermal enhancement. Pin 1 = VIN, Pin 2 = GND, Pin 3 = EN, Pin 4 = NC, Pin 5 = VOUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input power supply | Accepts 3.9–40V; requires ≥2.2µF ceramic bypass capacitor placed adjacent to minimize trace inductance and suppress transients. |
| GND (Pin 2) | Reference ground | Must connect directly to low-impedance PCB ground plane; forms return path for all internal currents and feedback sensing. |
| EN (Pin 3) | Enable control input | Active-high logic: >1.5V enables regulator; <1.21V disables it. Must not float - tie to VIN or MCU GPIO via pull-up if unused. |
| NC (Pin 4) | No internal connection | May be left unconnected or tied to GND for mechanical stability; no electrical function or signal routing required. |
| VOUT (Pin 5) | Regulated output | Delivers up to 150mA at 3.6V; requires ≥2.2µF ceramic capacitor to GND for stability; place capacitor within 2mm of pin for optimal transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 3.8µA enables >10-year battery life in coin-cell–powered devices such as smart meters or wireless sensor nodes. |
| Integrated enable control | EN pin with 1.5V threshold and hysteresis allows precise power sequencing with microcontrollers or discrete logic without external level shifters. |
| UVLO with hysteresis | 2.42V rising / 2.2V falling thresholds prevent oscillation during noisy or sagging input conditions, ensuring clean startup and shutdown. |
| Stable with minimal capacitance | Guaranteed stability using only 2.2µF ceramic output capacitor - reduces BOM count and PCB area vs. legacy LDOs requiring 10µF+ tantalum. |
| Over-temperature protection | 150°C shutdown with 20°C hysteresis provides fail-safe thermal management without external monitoring circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B362MR-G | 3.6V, 150mA, SOT-23-5, IQ = 1.2µA, dropout = 250mV @ 100mA, no EN pin | Lacks enable control and UVLO; requires external enable circuitry for sequencing | Select when lowest possible IQ is critical and enable functionality is implemented externally. |
| ROHM BD3572EFJ-ME2 | 3.6V, 200mA, HTSOP-8, IQ = 50µA, dropout = 300mV @ 100mA, includes EN and thermal shutdown | Higher IQ and larger 8-pin package; better thermal performance (θJA = 60°C/W) but less suitable for ultra-compact designs | Select when higher output current or improved thermal margin is required and board space permits larger footprint. |
Compared with XC6210B362MR-G and BD3572EFJ-ME2, RAA2144044GP3#JA0 uniquely balances ultra-low IQ (3.8µA), integrated EN/UVLO/thermal protection, and SOT-23-5 compactness - making it optimal for space- and battery-limited applications where full feature integration is non-negotiable.

FAQ
What is the maximum input voltage rating for RAA2144044GP3#JA0?
The RAA2144044GP3#JA0 has an absolute maximum input voltage rating of +45V and a recommended operating input range of 3.9V to 40V. This 40V upper limit ensures reliable regulation across industrial and automotive supply rails, while the 45V transient tolerance accommodates load dump events without damage or latch-up.
Does RAA2144044GP3#JA0 require an external enable pull-up resistor?
Yes - the EN pin of RAA2144044GP3#JA0 must not be left floating. When interfacing with open-drain/open-collector logic or unused, a 1kΩ to 10kΩ pull-up resistor to VIN is required to ensure proper HIGH-level enable. The EN threshold is 1.5V typical, so the pull-up must guarantee VEN exceeds this value under all operating conditions.
Can RAA2144044GP3#JA0 operate stably with a 2.2µF output capacitor?
Yes - RAA2144044GP3#JA0 is explicitly characterized and guaranteed stable with a minimum 2.2µF X5R/X7R ceramic output capacitor. This eliminates reliance on larger, higher-ESR tantalum or aluminum electrolytic capacitors, reducing size, cost, and aging-related drift in long-life applications.
What is the typical dropout voltage of RAA2144044GP3#JA0 at 100mA load?
The typical dropout voltage of RAA2144044GP3#JA0 at 100mA load is 495mV, with a maximum of 803mV across temperature and process variation. This enables regulation from as low as 4.095V input, supporting operation during deep battery discharge or low-headroom industrial supply conditions.
How does the thermal shutdown protection work in RAA2144044GP3#JA0?
RAA2144044GP3#JA0 activates over-temperature shutdown at a junction temperature of approximately 150°C, disabling the output until the die cools by 20°C hysteresis (to ~130°C). This prevents thermal runaway during sustained overload or high ambient conditions while avoiding oscillatory behavior near the trip point.
