Product details
Overview
RAA2144034GP3#JA0 from Renesas Electronics is a 3.3V fixed-output, low-quiescent current (3.8µA) PMOS LDO regulator in a 5-pin SOT-23 package, delivering up to 150mA with ±3% output voltage accuracy over line/load/temperature and 40V max input voltage. It serves as a primary power rail for ultra-low-power microcontrollers in battery-powered industrial sensors.
For engineers reviewing the RAA2144034GP3#JA0 datasheet, RAA2144034GP3#JA0 pinout, RAA2144034GP3#JA0 application, or RAA2144034GP3#JA0 equivalent, key selection criteria include its 0.5V dropout at 100mA, UVLO hysteresis (2.2V rising / 2.2V falling), enable-controlled shutdown (<0.5µA), thermal shutdown at +150°C, and stability with only 2.2µF ceramic output capacitance.
Technical Context
The RAA2144034GP3#JA0 implements a PMOS pass transistor architecture with internal bandgap reference and error amplifier feedback loop, enabling precise DC regulation under dynamic load steps. Its UVLO circuit incorporates 200mV hysteresis to prevent oscillation during input voltage droop, while the enable control path features dedicated VEN threshold detection (1.5V typical) with hysteresis for noise immunity.
Protection functions are fully integrated: short-circuit current limiting (250mA typ) operates independently of thermal shutdown (+150°C trip with 20°C hysteresis), and ground current scales linearly with load (36µA at 10mA, 159µA at 150mA), ensuring predictable thermal behavior across operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3V ±3% - guarantees stable MCU core voltage across -40°C to +125°C junction temperature, 4.5–40V input range, and 0–150mA load. |
| Quiescent Current | 3.8µA typical - enables >10-year battery life in always-on IoT sensor nodes powered by CR2032 cells. |
| Dropout Voltage | 510mV at 100mA - allows regulation from 3.81V input, critical for brownout resilience in automotive body electronics. |
| Input Voltage Range | 4.5V to 40V - supports direct connection to 24V industrial buses and 36V battery packs without external pre-regulation. |
| Output Capacitor | 2.2µF min ceramic - eliminates need for tantalum or electrolytic capacitors, reducing BOM cost and board area in space-constrained wearables. |
| Enable Threshold | 1.5V typical rising - compatible with 1.8V/3.3V GPIOs and resistor-divider programming for custom turn-on voltage sequencing. |
| Thermal Shutdown | +150°C trip with 20°C hysteresis - prevents permanent damage during sustained overload while allowing recovery without manual reset. |
Pinout & Package
RAA2144034GP3#JA0 uses a 5-lead SOT-23 package with exposed thermal pad (GND-connected) for enhanced heat dissipation. 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 4.5–40V; requires ≥2.2µF ceramic bypass capacitor placed adjacent to pin to suppress high-frequency noise from upstream switching converters. |
| GND (Pin 2) | Reference ground | Must connect directly to PCB ground plane; serves as return path for all internal currents and thermal pad anchor point. |
| EN (Pin 3) | Enable control input | Active-high logic: <1.21V disables LDO (shutdown current <0.5µA), >1.5V enables; must not float-tie to VIN if unused. |
| NC (Pin 4) | No internal connection | Electrically isolated; may be left floating or tied to GND for mechanical stability-no electrical impact on regulation. |
| VOUT (Pin 5) | Regulated output | Delivers 3.3V ±3% to load; requires ≥2.2µF ceramic capacitor from VOUT to GND, placed within 2mm of pin for transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 3.8µA quiescent current enables multi-year operation from coin-cell batteries in remote monitoring devices. |
| Integrated UVLO with hysteresis | 2.2V rising / 2.2V falling threshold prevents erratic startup during weak-battery conditions or long cable drops. |
| PMOS pass transistor architecture | Eliminates need for external bias supply; achieves low dropout while maintaining stability with minimal output capacitance. |
| Robust protection suite | Combines current limiting (250mA), thermal shutdown (+150°C), and input overvoltage tolerance (45V transient) for unregulated industrial environments. |
| Small-footprint packaging | 5-pin SOT-23 (2.9mm × 1.6mm) reduces PCB area by 60% vs. comparable SOT-89 regulators, ideal for wearable medical patches. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B332MR-G | 3.3V output, 150mA, 2.5µA IQ, SOT-23-5 - lacks enable pin and UVLO; no thermal shutdown. | Suitable only for simple always-on circuits without sequencing or fault protection requirements. | Select when lowest possible IQ is critical and system-level protection is handled externally. |
| ROHM BD33C0AWP-E2 | 3.3V output, 150mA, 60µA IQ, SOT-23-5 - includes enable but higher IQ; no UVLO hysteresis or 45V transient rating. | Better for cost-sensitive consumer devices where battery life >1 year is not required. | Choose when PCB layout constraints match and thermal/overvoltage robustness is secondary to BOM cost. |

FAQ
What is the maximum input voltage the RAA2144034GP3#JA0 can tolerate during transients?
The RAA2144034GP3#JA0 supports 45V absolute maximum input voltage per datasheet Section 3.1, enabling reliable operation during automotive load-dump events and industrial power-line surges without external clamping. This rating applies to short-duration transients; continuous operation must remain within the 4.5–40V recommended range. The 45V tolerance is validated per JEDEC standards and does not require derating for ambient temperature.
Does the RAA2144034GP3#JA0 require an external pull-up resistor on the EN pin?
Yes-the EN pin of RAA2144034GP3#JA0 must not be left floating. When interfacing with open-drain/open-collector logic, a 1kΩ–10kΩ pull-up resistor to VIN is required to ensure proper HIGH-level recognition (VEN > 1.5V). If EN is permanently enabled, it must be tied directly to VIN-not to a separate 3.3V rail-to guarantee correct UVLO interaction and startup sequencing.
Can the RAA2144034GP3#JA0 operate stably with a 1µF output capacitor?
No-RAA2144034GP3#JA0 requires a minimum 2.2µF ceramic output capacitor for guaranteed stability across -40°C to +125°C, as specified in Section 1 and Figure 1. Using 1µF violates the stability criterion and risks oscillation, especially under load transients. Renesas validates performance only with ≥2.2µF X5R/X7R MLCCs; smaller values may cause VOUT overshoot/undershoot exceeding ±5%.
What is the thermal resistance (θJA) of the RAA2144034GP3#JA0 in its SOT-23 package?
The RAA2144034GP3#JA0 has a junction-to-ambient thermal resistance (θJA) of 174°C/W when mounted on a standard high-thermal-conductivity test board per JEDEC JESD51-2, as stated in Section 3.3. This value assumes optimal PCB layout: 1-inch² copper pour connected to the exposed thermal pad, 2oz copper, and no nearby heat sources. Real-world θJA may vary ±25% based on actual board design and airflow.
How does the RAA2144034GP3#JA0 behave during thermal shutdown?
When the RAA2144034GP3#JA0 junction temperature reaches +150°C, it initiates over-temperature shutdown (OTSD), disabling the output and reducing IOUT to 0mA. The device remains latched off until the die cools by 20°C (to +130°C), at which point it automatically recovers. During OTSD, VOUT collapses to near 0V, and quiescent current drops to <1µA-preventing thermal runaway while enabling autonomous recovery without system intervention.
