Product details
Overview
RAA2144014GP3#NA0 from Renesas Electronics is a fixed-output 3.3V, 150mA low-dropout linear regulator with ultra-low 3.6µA quiescent current, wide 4.5V–40V input range, integrated over-temperature shutdown and short-circuit current limit, and stable operation with 2.2µF–200µF MLCC output capacitors - designed for always-on battery-powered MCU standby supplies.
For engineers reviewing the RAA2144014GP3#NA0 datasheet, RAA2144014GP3#NA0 pinout, RAA2144014GP3#NA0 application, or RAA2144014GP3#NA0 equivalent, this page delivers verified electrical specs, SOT23-3 package details, thermal protection behavior, load/line regulation performance, and real-world use cases in electric meters and portable modules.
Technical Context
The RAA2144014GP3#NA0 implements a high-stability LDO architecture with internal resistor-based 3.3V feedback, delivering ±3% output voltage accuracy across –40°C to +125°C junction temperature and full 4.5V–40V input range. Its dropout voltage ranges from 0.96V at 10mA to 1.6V at 150mA, enabling reliable regulation under high-VIN/low-VOUT conditions.
It integrates dual fault protections: thermal shutdown activates at 155°C with 17.5°C hysteresis, and short-circuit current limit holds output at 150mA when VOUT drops to 1V. PSRR reaches 77dB at 10Hz and remains >42dB up to 10kHz, supporting noise-sensitive analog and digital loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±3% (3.20–3.39V), internally trimmed for stability across temperature and load. |
| Max Output Current | 150mA continuous, limited by internal current foldback during overload or short circuit. |
| Quiescent Current | 3.6µA typical at no load and VIN = 6V - enables multi-year battery life in keep-alive systems. |
| Input Voltage Range | 4.5V to 40V (at 1mA load); minimum rises to 4.9V at 150mA - supports automotive load-dump transients. |
| Line Regulation | 0.0003–0.005%/V - ensures <1.5mV output shift per volt input change, critical for precision sensing rails. |
| Load Regulation | 0.0025–0.006%/mA - maintains <0.9mV output deviation from 0.1mA to 150mA load step. |
| PSRR @ 100Hz | 74dB - suppresses 100Hz ripple from upstream switching converters by >5,000×. |
Pinout & Package
RAA2144014GP3#NA0 is housed in a RoHS-compliant 3-lead SOT23-3 plastic package (Pkg. Dwg. P3.064B), with 0.95mm max height, 1.3mm × 2.9mm footprint, and e3 matte tin termination for Pb-free reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Analog input supply | Accepts 4.5–40V input; requires ≥0.1µF ceramic decoupling to GND close to pin for EMI immunity and transient response. |
| VOUT (Pin 2) | Regulated output | Delivers stable 3.3V; must connect 2.2–200µF X7R MLCC directly to GND with minimal trace length to ensure stability. |
| GND (Pin 3) | Ground reference | Common return path for input/output capacitors and load; connects to PCB ground plane to minimize impedance and improve thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 3.6µA quiescent current enables >10-year battery life in 10µA-system standby applications. |
| Wide VIN range | 4.5–40V operation supports 12V/24V industrial and automotive systems, including load-dump survival. |
| Thermal shutdown | 155°C trip with 17.5°C hysteresis prevents permanent damage during sustained overload or poor heatsinking. |
| Capacitor flexibility | Stable with 2.2–200µF MLCC output caps - eliminates need for tantalum or electrolytic, reducing BOM cost and size. |
| High PSRR | 77dB at 10Hz and >52dB up to 1kHz - isolates sensitive analog circuits from noisy DC/DC sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS7A0533PDBVR | 3.3V/200mA, 25µA IQ, 1.8–6V input - narrower VIN range, higher IQ, smaller SOT23-5 package. | Not suitable for 24V+ systems or long-life battery apps; better for space-constrained 5V-fed designs. | Select only if input stays ≤6V and PCB area is premium; not a drop-in replacement due to different pinout and voltage range. |
| ON Semi NCP1117ST33T3G | 3.3V/1A, 6mA IQ, 4.75–20V input - higher current, much higher IQ, TO-220/SOT-223 packages. | Over-specified for 150mA/low-IQ needs; unsuitable for compact, battery-operated devices. | Choose only for high-current, non-battery applications where thermal mass offsets IQ penalty; incompatible SOT23 footprint. |
Compared with TPS7A0533PDBVR and NCP1117ST33T3G, the RAA2144014GP3#NA0 uniquely balances ultra-low IQ (3.6µA), 40V input capability, and SOT23-3 compactness - making it the sole option for space- and energy-constrained 12–24V always-on systems requiring >5-year battery life.

FAQ
What is the maximum input voltage rating for RAA2144014GP3#NA0?
The RAA2144014GP3#NA0 has an absolute maximum input voltage of +45V, but its recommended operating range is 4.5V to 40V at 1mA load - and 4.9V to 40V at full 150mA load. This 40V upper limit allows safe operation during automotive load-dump transients. Exceeding 45V risks permanent damage per the Absolute Maximum Ratings table on page 4 of the R16DS0268EU0201 datasheet.
Does RAA2144014GP3#NA0 require an external resistor network to set output voltage?
No, the RAA2144014GP3#NA0 features a factory-trimmed internal resistor network that fixes the output voltage at 3.3V - no external resistors are needed or supported. The device is not adjustable; all variants (including RAA2144014GP3#NA0) deliver precisely 3.3V ±3% across temperature and load, as confirmed in Section 2.4 Electrical Specifications on page 5 of the datasheet.
What output capacitor value is required for stable operation of RAA2144014GP3#NA0?
The RAA2144014GP3#NA0 is stable with any X7R-type MLCC output capacitor between 2.2µF and 200µF, as specified in Section 5.1 and Table 2.3. A 10µF or 22µF X7R cap is commonly used to balance transient response and board space. Values below 2.2µF risk oscillation; values above 200µF are unnecessary and may slow startup time without benefit.
How does thermal shutdown behave in RAA2144014GP3#NA0?
The RAA2144014GP3#NA0 triggers over-temperature shutdown at 155°C junction temperature and remains off until die temperature falls to ~137.5°C (155°C – 17.5°C hysteresis), as detailed in Section 2.4 and 4.3. During shutdown, VOUT collapses and IGND drops to near-zero. Recovery is automatic once thermal limits are restored - no reset pin or external intervention is required.
Is RAA2144014GP3#NA0 compatible with standard SOT23-3 footprints?
Yes, RAA2144014GP3#NA0 uses the industry-standard 3-lead SOT23-3 package (drawing P3.064B), with 0.95mm max height, 1.3mm × 2.9mm body, and 0.95mm lead pitch - fully compatible with IPC-7351B SOT23-3 land patterns. Pin 1 (VIN) is marked by a dot or beveled edge; orientation matches JEDEC MO-178AB standards per page 12 of the datasheet.
