Product details
Overview
RAA2142234GP3#JA0 from Renesas Electronics is a fixed-output 3.3V, 150mA low-dropout linear voltage regulator in a 5-pin TSOT23 package, operating across 4V–20V input range with 240mV typical dropout at full load and stable operation using only a 1µF MLCC output capacitor. It delivers precise regulation for MCU power rails in battery-powered and portable industrial equipment.
For engineers reviewing the RAA2142234GP3#JA0 datasheet, RAA2142234GP3#JA0 pinout, RAA2142234GP3#JA0 application, or RAA2142234GP3#JA0 equivalent, key selection criteria include its wide VIN range, ultra-low 3.6µA shutdown current, ±1.75%/+2.5% output accuracy over temperature, integrated thermal shutdown and current limit protection, and compatibility with minimal 1µF ceramic output capacitance.
Technical Context
The RAA2142234GP3#JA0 implements a high-PSRR LDO architecture with internal bandgap reference, error amplifier, and pass transistor, supporting enable-controlled startup and shutdown. Its EN pin features accurate 1.35–1.65V rising threshold and 1.275V falling threshold for reliable sequencing.
Thermal protection uses an over-temperature shutdown (OTSD) circuit with 155°C trip point and 22°C hysteresis, while short-circuit current limiting holds output current to 160–275mA independent of VOUT. The device achieves 86dB PSRR at 100Hz and maintains stability with X5R/X7R MLCCs ≥1µF on VOUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V with ±1.75%/+2.5% accuracy across –40°C to +125°C junction temperature |
| Max Output Current | 150mA continuous; supports full-load operation without thermal shutdown under proper PCB layout |
| Input Voltage Range | 4V to 20V DC - enables direct use with 5V, 12V, and 19V adapter inputs or multi-cell battery stacks |
| Dropout Voltage | 240mV typical at 150mA - allows regulation down to VIN = 3.54V while maintaining 3.3V output |
| Shutdown Current | 3.6µA at VIN = 4.5V - minimizes battery drain during system sleep modes |
| Output Capacitor | Stable with ≥1µF X5R/X7R MLCC - eliminates need for large tantalum or electrolytic capacitors |
| PSRR @ 100Hz | 86dB - suppresses ripple from noisy switcher outputs or shared input rails |
| Thermal Shutdown | 155°C trip with 22°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking |
Pinout & Package
The RAA2142234GP3#JA0 is housed in a RoHS-compliant 5-pin TSOT23 package (MDP0049), measuring 2.90mm × 2.80mm × 1.00mm with 0.95mm lead pitch. The package features exposed pad thermal enhancement and is rated for –40°C to +125°C operating junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Analog input supply | Primary power input; requires ≥0.1µF high-frequency ceramic decoupling to GND near pin |
| GND (Pin 2) | Ground reference | Common return path for input/output currents and internal bias; must connect to low-impedance ground plane |
| EN (Pin 3) | Enable control input | Active-high logic input; drives device ON above 1.35V, OFF below 1.275V; supports resistor-divider sequencing |
| OCFF (Pin 4) | Optional feedforward node | No connection required; optional 10–22pF capacitor to VOUT improves transient response and PSRR at select frequencies |
| VOUT (Pin 5) | Regulated 3.3V output | Delivers up to 150mA; requires ≥1µF X5R/X7R MLCC placed adjacent to pin for stability |
Key Features
| Feature | Design Value |
|---|---|
| Wide 4V–20V input range | Supports direct integration into systems powered by USB PD, 12V industrial rails, or 3–4S Li-ion batteries without pre-regulation |
| 1µF minimum output capacitance | Reduces BOM cost and board area versus legacy LDOs requiring ≥10µF; compatible with compact 0402/0603 MLCCs |
| 3.6µA shutdown current | Extends battery life in always-on sensor nodes or metering applications where EN is asserted only during active measurement cycles |
| Integrated OTSD and current limit | Eliminates need for external thermal sensors or foldback circuits; provides autonomous fault recovery after overload removal |
| 86dB PSRR at 100Hz | Enables clean 3.3V supply for noise-sensitive analog peripherals (ADCs, sensors) when sharing input with switching regulators |
| Accurate EN threshold (1.35–1.65V) | Allows robust power sequencing using simple resistor dividers from higher-voltage rails, reducing component count vs. dedicated supervisors |

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 fixed, 150mA, SOT-25 package; 220mV dropout at 150mA; 1µF min COUT; no EN pin | Lacks enable control - unsuitable for sequenced or low-power sleep systems | Select when EN functionality is unnecessary and footprint compatibility with SOT-25 is prioritized |
| ROHM BD33C0AWFP-E2 | 3.3V fixed, 200mA, HTSOP-J8 package; 300mV dropout at 200mA; 10µF min COUT; includes EN and CL discharge | Higher dropout and larger 10µF output cap requirement increases size/cost; CL discharge aids fast turn-off | Choose when higher output current is needed and board space allows larger package and capacitor |
Compared with RAA2142234GP3#JA0, the XC6210B332MR-G omits enable control but matches dropout and capacitor requirements in a pin-compatible SOT-25, while the BD33C0AWFP-E2 offers higher current at the cost of increased dropout and mandatory 10µF output capacitance - making RAA2142234GP3#JA0 optimal for space-constrained, enable-driven, low-quiescent designs.

FAQ
What is the maximum input voltage rating for RAA2142234GP3#JA0?
The absolute maximum input voltage for RAA2142234GP3#JA0 is +22V, but the recommended operating range is +4V to +20V DC. Operation beyond 20V voids guaranteed performance and may impact reliability. The device's internal protection circuits do not extend safe operation beyond the absolute maximum rating, so design margins should maintain VIN ≤20V under all conditions including transients.
Does RAA2142234GP3#JA0 require an external feedforward capacitor on the OCFF pin?
No, the OCFF pin on RAA2142234GP3#JA0 is optional and does not require connection. A 10–22pF ceramic capacitor between OCFF and VOUT may improve transient response and PSRR at specific frequencies, but the device remains fully stable and functional with OCFF left unconnected - simplifying layout and reducing BOM count.
Can RAA2142234GP3#JA0 operate with a 1µF output capacitor over temperature and process variation?
Yes, RAA2142234GP3#JA0 is characterized and guaranteed stable with a minimum 1µF X5R or X7R MLCC output capacitor across –40°C to +125°C junction temperature and full process variation. Renesas validates this stability per JEDEC standards, and the datasheet specifies 1µF as the absolute minimum - no derating is required for production use.
What is the thermal resistance (θJA) of RAA2142234GP3#JA0 in its TSOT23 package?
The junction-to-ambient thermal resistance (θJA) of RAA2142234GP3#JA0 in the 5-pin TSOT23 package is 215°C/W, measured on a high-thermal-conductivity test board per JEDEC JESD51-2. Actual θJA in end equipment depends on PCB copper area, layer stack-up, and airflow; adding thermal vias under the exposed pad can reduce effective θJA by 20–40%.
How does the enable threshold of RAA2142234GP3#JA0 support power sequencing with a 12V rail?
The RAA2142234GP3#JA0 EN pin has a guaranteed rising threshold of 1.35–1.65V, enabling reliable sequencing from a 12V rail using a simple two-resistor divider (e.g., 100kΩ + 12.4kΩ). This avoids the need for discrete supervisors or level shifters, and the 1.275V falling threshold ensures clean shutdown during brownout - critical for deterministic MCU reset behavior in RAA2142234GP3#JA0-based systems.
