Product details
Overview
RAA2142904GSP#HA0 from Renesas Electronics is a 1A adjustable-output linear voltage regulator (LDO) with 2.5V–20V input range, 540mV typical dropout at 1A, and output programmable from 1.224V to 18V using external resistors. It delivers stable power to MCU cores, USB peripherals, and portable metering systems with ultra-low 3μA shutdown current.
For engineers reviewing the RAA2142904GSP#HA0 datasheet, RAA2142904GSP#HA0 pinout, RAA2142904GSP#HA0 application, or RAA2142904GSP#HA0 equivalent, key selection criteria include dropout performance at full load, ground current vs. load profile, UVLO hysteresis, thermal shutdown behavior, and stability with minimal 2.2μF ceramic output capacitance.
Technical Context
The RAA2142904GSP#HA0 employs a PMOS pass transistor architecture enabling low dropout and high PSRR (95dB at 100Hz). Its error amplifier compares the ADJ pin voltage (internally referenced to 1.224V) against feedback from an external resistor divider to regulate VOUT dynamically across line, load, and temperature variations.
Integrated protection includes input UVLO with 200mV hysteresis, enable-controlled shutdown with 1.35–1.65V threshold and 125–245mV hysteresis, foldback short-circuit current limiting (430mA at VIN–VOUT = 18V), and over-temperature shutdown at 150°C with 20°C hysteresis - all implemented in a single monolithic die.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 20V - supports wide-input industrial and battery-powered systems without pre-regulation. |
| Max Output Current | 1A continuous - sufficient for powering mid-power MCUs, sensors, and interface ICs. |
| Dropout Voltage | 540mV typical at 1A - enables regulation from 3.3V input to 2.76V output, critical for low-headroom applications. |
| Ground Current | 80μA at no load, 3μA in shutdown - extends battery life in always-on and sleep-mode devices. |
| Output Voltage Range | 1.224V to 18V adjustable - covers standard logic rails (1.8V, 3.3V, 5V) and higher analog/industrial supplies. |
| Stability Capacitance | Stable with ≥2.2μF X5R/X7R ceramic output capacitor - reduces BOM cost and board area vs. larger electrolytics. |
| PSRR | 95dB at 100Hz, 70dB at 10kHz - suppresses switching noise from upstream DC/DC converters. |
Pinout & Package
RAA2142904GSP#HA0 is packaged in an 8-lead 3mm × 3mm DFN with exposed thermal pad (EPAD), optimized for thermal dissipation in space-constrained designs. Pinout matches the DFN variant shown in Figure 2.2 of R16DS0348EU0103 Rev.1.03.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pins 1,2) | Regulated output supply | Dual-source pins reduce IR drop and improve current sharing; requires ≥2.2μF capacitor to GND for stability. |
| ADJ (Pin 3) | Feedback reference node | Internally biased to 1.224V; external resistor divider sets VOUT per VOUT = 1.224V × (1 + RF/RG). |
| GND (Pin 5) | Analog and power ground | Mandatory connection to PCB ground plane; EPAD must be soldered to same plane for thermal and electrical integrity. |
| EN (Pin 6) | Enable control input | Active-high logic; 1.35–1.65V threshold with hysteresis prevents chatter during slow-rising control signals. |
| VIN (Pins 7,8) | Input power supply | Dual-input pins lower trace resistance; requires 10μF bulk + 1μF local ceramic capacitor to GND. |
| EPAD | Thermal and electrical ground | Exposed copper pad on package underside; must be soldered to PCB ground plane for θJC = 14°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (2.5V–20V) | Eliminates need for intermediate regulators in multi-rail systems powered by 5V, 12V, or Li+ batteries. |
| Foldback short-circuit protection | Reduces fault current to 430mA under high VIN–VOUT differential, limiting power dissipation during sustained shorts. |
| UVLO with 200mV hysteresis | Prevents erratic startup during brown-out conditions caused by long cables or weak sources. |
| Low-noise operation (173µVRMS) | Meets stringent noise requirements for precision ADCs, DACs, and RF front-end biasing. |
| Thermal shutdown with 20°C hysteresis | Enables safe auto-recovery after overload without requiring external reset circuitry. |
Applications
| Battery-Powered Equipment | MCU Power Supply |
|---|---|
Use Scenario: Portable gas detector with Li-ion battery (2.8V–4.2V) powering 3.3V MCU and analog sensor chain. IC Role / Device Role / Timing Role: Primary LDO delivering regulated 3.3V rail with <100mV dropout margin at end-of-discharge. Use Value: 3μA shutdown current extends shelf life; 173µVRMS noise avoids ADC quantization errors. |

IC Role / Device Role / Timing Role: Secondary LDO generating 3.3V I/O supply from 5V backplane, synchronized via EN pin to MCU boot sequence. Use Value: 95dB PSRR at 100Hz rejects ripple from shared 5V DC/DC; 1.224V min output supports future low-voltage peripherals. |
| Electric Meters | USB Devices |
Use Scenario: DIN-rail mounted smart electricity meter with isolated 12V auxiliary supply powering metrology ASIC and RTC. IC Role / Device Role / Timing Role: Adjustable LDO set to 3.3V for metrology IC and 1.8V for RTC, both derived from same 12V input. Use Value: Single-part solution replaces dual fixed-LDOs; 2.2μF stability enables compact layout in sealed enclosure. |
Use Scenario: USB-C powered portable SSD with 5V bus supplying 3.3V controller and 1.2V NAND flash interface. IC Role / Device Role / Timing Role: Load-switch-capable LDO regulating 3.3V rail, enabled only when USB enumeration completes. Use Value: EN pin threshold accuracy allows direct connection to USB PD controller GPIO; 540mV dropout ensures regulation down to 3.83V bus voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TPS7A4700RGWR | Fixed 3.3V output, ±0.5% accuracy, 1A, 310mV dropout at 1A, 2.2μF stable, SO-8 package. | Lacks adjustability and wider input range (2.9V–20V); no UVLO or foldback protection. | Select when fixed 3.3V output suffices and lowest possible dropout is prioritized over flexibility. |
| Analog Devices ADM7172ACPZ-R7 | 1A, 2.3V–6.5V input, 1.2V–5.5V adjustable output, 120mV dropout at 1A, 10μF minimum COUT. | Narrower input range excludes 12V/20V systems; higher COUT requirement increases footprint and cost. | Choose for ultra-low-dropout needs in sub-6.5V systems where thermal headroom is constrained. |
Compared with TPS7A4700RGWR and ADM7172ACPZ-R7, RAA2142904GSP#HA0 uniquely combines 2.5V–20V input support, 1.224V–18V adjustability, foldback protection, and 2.2μF stability - making it optimal for multi-voltage industrial and battery-backed applications where design reuse across platforms matters.

FAQ
What is the minimum output capacitor required for stable operation of RAA2142904GSP#HA0?
The RAA2142904GSP#HA0 is stable with a minimum 2.2μF X5R or X7R ceramic output capacitor. This value is verified across -40°C to +125°C and supports full 1A load step response without oscillation. Larger values improve transient performance but are not required for basic stability. The capacitor must be placed close to VOUT and GND pins.
Does RAA2142904GSP#HA0 support adjustable output voltage, and how is it configured?
Yes, RAA2142904GSP#HA0 supports adjustable output from 1.224V to 18V using two external resistors (RF and RG) connected between VOUT, ADJ, and GND. The ADJ pin is internally referenced to 1.224V, and VOUT = 1.224V × (1 + RF/RG). Table 1 in the datasheet provides recommended resistor values for common rails like 3.3V and 5V.
What protection features does RAA2142904GSP#HA0 include?
RAA2142904GSP#HA0 integrates input UVLO with 200mV hysteresis, enable-controlled shutdown (3μA IQ), foldback short-circuit current limiting (430mA at high VIN–VOUT), and over-temperature shutdown at 150°C with 20°C hysteresis. These features operate autonomously without external components.
What is the typical dropout voltage of RAA2142904GSP#HA0 at full 1A load?
The typical dropout voltage of RAA2142904GSP#HA0 is 540mV at 1A output current and 25°C ambient temperature. This value increases to 1150mV maximum across -40°C to +125°C. Dropout is measured as the VIN–VOUT difference when VOUT drops 100mV below nominal regulation.
Is RAA2142904GSP#HA0 compatible with standard SOIC-8 footprints?
No, RAA2142904GSP#HA0 uses an 8-lead 3mm × 3mm DFN package with exposed thermal pad (EPAD), not SOIC-8. It is pin-compatible with the RAA214290 DFN variant but incompatible with SOIC-8 land patterns. Thermal performance relies on proper EPAD soldering to the PCB ground plane.
