Product details
Overview
RAA2144054GP3#JA0 from Renesas Electronics is a 5V 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 microcontroller peripherals in battery-powered industrial sensors.
For engineers reviewing the RAA2144054GP3#JA0 datasheet, RAA2144054GP3#JA0 pinout, RAA2144054GP3#JA0 application, or RAA2144054GP3#JA0 equivalent, key selection criteria include dropout voltage at 100mA (≤737mV), enable control logic thresholds (1.3–1.68V rising), UVLO hysteresis (2.2V ±0.22V), thermal shutdown (150°C), and stability with 2.2µF ceramic output capacitance.
Technical Context
This LDO uses a PMOS pass transistor architecture with internal bandgap reference and error amplifier feedback loop to maintain regulation across load steps and input transients. Its UVLO circuit disables operation below 2.15V with 220mV hysteresis, preventing erratic startup during brownout conditions.
The enable function (EN pin) provides precise logic-level control with 1.5V typical threshold and 121mV hysteresis, supporting direct MCU GPIO interfacing or resistor-divider programming. Shutdown current is <0.5µA, making it suitable for ultra-low-power wake-on-event systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0V ±3% - ensures stable supply for 5V-tolerant logic and analog circuits across full temperature range (-40°C to +125°C) |
| Max Input Voltage | 40V - supports wide-range industrial DC inputs including 24V and 36V rails with 45V transient tolerance |
| Quiescent Current | 3.8µA - enables multi-year battery life in always-on sensor nodes with infrequent wake cycles |
| Dropout Voltage | 737mV at 150mA - allows regulation down to VIN = 5.737V, critical for maintaining output during battery discharge |
| Output Accuracy | ±3% over line/load/temp - eliminates need for external trimming in cost-sensitive embedded designs |
| Thermal Shutdown | 150°C with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design |
| Enable Threshold | 1.5V rising (1.21V falling) - compatible with 1.8V/3.3V GPIO without level-shifting |
Pinout & Package
RAA2144054GP3#JA0 is housed in a RoHS-compliant 5-lead SOT-23 package with exposed thermal pad (GND-connected). Pin 1 is VIN, Pin 2 is GND, Pin 3 is EN, Pin 4 is NC (no internal connection), and Pin 5 is VOUT. The NC pin may be left floating or tied to GND for mechanical stability.
| 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 and prevent instability |
| GND (Pin 2) | Reference ground | Must connect directly to low-impedance PCB ground plane; also ties exposed thermal pad for optimal heat dissipation |
| EN (Pin 3) | Enable control input | Active-high logic: drives LDO ON when >1.5V, OFF when <1.21V; must not float-tie to VIN or MCU GPIO with pull-up if unused |
| NC (Pin 4) | No internal connection | Electrically isolated; may be left unconnected or grounded for mechanical reinforcement-no electrical impact on regulation |
| VOUT (Pin 5) | Regulated output | Delivers 5V ±3% up to 150mA; requires ≥2.2µF ceramic capacitor to GND; placement within 2mm of pin minimizes ESR-induced ripple |
Key Features
| Feature | Design Value |
|---|---|
| Low IQ operation | 3.8µA quiescent current enables >10-year battery life in 250µA average-load IoT endpoints |
| UVLO with hysteresis | 2.42V rising / 2.2V falling threshold prevents oscillation during input voltage sag from long cables or shared supplies |
| PMOS pass transistor | Enables low dropout and no reverse-current flow-critical for back-powering prevention in multi-rail systems |
| Stable with small ceramics | Guaranteed stability with 2.2µF X5R/X7R MLCC eliminates need for larger, higher-ESR tantalum or electrolytic capacitors |
| Over-temperature protection | 150°C shutdown with 20°C hysteresis avoids thermal runaway while allowing safe recovery after transient overload |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6219B502MR-G | Same 5V output, but only 100mA rated; 2.5µA IQ; no EN pin; SOT-23-5 package | Lacks enable control and thermal shutdown; unsuitable for systems requiring remote power sequencing or fault protection | Select only for space-constrained, non-critical 5V rails where enable and protection are handled externally |
| ON Semiconductor NCP1117ST50T3G | 5V output, 1A rating, 6mA IQ, TO-220/SOT-223; no EN or UVLO; higher dropout (1.1V @ 100mA) | Higher power capability but significantly higher IQ and no low-power features; lacks integrated protection | Choose only for high-current, non-battery applications where thermal management is prioritized over efficiency |
Compared with XC6219B502MR-G and NCP1117ST50T3G, RAA2144054GP3#JA0 uniquely combines ultra-low IQ (3.8µA), integrated EN control, UVLO, thermal shutdown, and 150mA capability in a compact SOT-23-5-making it the sole option for battery-powered industrial nodes requiring both longevity and robust fault handling.

FAQ
What is the maximum input voltage rating for RAA2144054GP3#JA0?
The RAA2144054GP3#JA0 has an absolute maximum input voltage rating of +45V, with recommended operating range from 4.5V to 40V. This 40V upper limit ensures reliable operation in 24V industrial systems and accommodates transient spikes common in automotive and motor-control environments. Operation above 40V is permissible only for short-duration transients up to 45V, as specified in the Absolute Maximum Ratings table.
Does RAA2144054GP3#JA0 require an external enable pull-up resistor?
Yes, RAA2144054GP3#JA0 requires a pull-up resistor on the EN pin if driven by an open-drain or open-collector source (e.g., MCU GPIO configured as such). A 10kΩ resistor to VIN is recommended to ensure VEN exceeds the 1.5V rising threshold. If the EN pin is tied directly to a push-pull GPIO or VIN, no external resistor is needed-but leaving EN floating is strictly prohibited as it may cause unpredictable operation.
Can RAA2144054GP3#JA0 operate stably with a 1µF output capacitor?
No, RAA2144054GP3#JA0 is not guaranteed stable with a 1µF output capacitor. The datasheet specifies a minimum of 2.2µF ceramic (X5R/X7R) for unconditional stability across temperature, load, and input voltage ranges. Using 1µF risks oscillation, excessive output ripple, or failure to regulate under load transients-especially at high ambient temperatures or near maximum current.
What is the typical dropout voltage of RAA2144054GP3#JA0 at 100mA load?
The typical dropout voltage of RAA2144054GP3#JA0 at 100mA load is 474mV, with a maximum of 1017mV over temperature and process variation. This means the device maintains regulation as long as VIN remains ≥5.474V (5V + 474mV). The low dropout enables extended runtime from partially discharged batteries and compatibility with tightly regulated intermediate bus voltages.
How does the UVLO feature protect RAA2144054GP3#JA0 during cold cranking in automotive applications?
The UVLO feature disables RAA2144054GP3#JA0 when input voltage falls below 2.15V (rising threshold) and re-enables only after VIN rises above 2.42V, providing 270mV hysteresis. During automotive cold cranking, where battery voltage can dip to 3–4V intermittently, this prevents the LDO from attempting regulation at unstable input levels-avoiding output droop, reset glitches, or uncontrolled current draw that could destabilize the entire system rail.
