Product details
Overview
RAA2142504GNP#HC0 from Renesas Electronics is a 500mA, wide-input (2.5V–20V) adjustable-output LDO linear regulator featuring 269mV typical dropout at full load, 1.224V–18V output voltage range set via external resistors, and ultra-low 2.4μA shutdown current - designed for MCU power rails, battery-powered instrumentation, and USB peripheral supplies.
For engineers reviewing the RAA2142504GNP#HC0 datasheet, RAA2142504GNP#HC0 pinout, RAA2142504GNP#HC0 application, or RAA2142504GNP#HC0 equivalent, key selection criteria include input UVLO threshold (2.08V rising), thermal shutdown with 20°C hysteresis, PSRR of 87dB at 100Hz, ground current stability across temperature (68μA typ. at 25°C), and compatibility with 2.2μF minimum X5R/X7R MLCC output capacitors.
Technical Context
The RAA2142504GNP#HC0 employs a PMOS pass transistor architecture enabling low dropout and high PSRR without requiring an external bias supply. Its internal bandgap reference (1.224V ±2% over –40°C to +125°C) feeds an error amplifier that drives the gate of the PMOS pass device through a stable compensation network.
Protection logic integrates independent UVLO (2.08V rising, 220mV hysteresis), enable-controlled shutdown (EN threshold: 1.35V–1.65V), foldback short-circuit current limiting (240–600mA depending on VIN–VOUT), and thermal shutdown (150°C trip, 130°C recovery) - all implemented in a single monolithic die with no external components required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 20V - supports direct regulation from 3.3V, 5V, 9V, 12V, and 19V nominal sources without pre-regulation. |
| Max Output Current | 500mA - sufficient for powering mid-performance MCUs, sensors, and interface ICs with margin. |
| Dropout Voltage | 269mV typical at 500mA - enables stable 3.3V output from 3.57V input, critical for battery end-of-life operation. |
| Output Voltage Range | 1.224V to 18V - adjustable via two external resistors; minimum setpoint matches internal reference for fixed 1.224V use. |
| Ground Current | 68μA typical at no-load, 2.4μA in shutdown - minimizes quiescent drain in always-on systems and extends battery life. |
| PSRR | 87dB at 100Hz, 63dB at 10kHz - suppresses ripple from switching converters feeding the LDO input. |
| Thermal Shutdown | 150°C trip with 20°C hysteresis - prevents latch-up during sustained overload or poor PCB thermal design. |
Pinout & Package
RAA2142504GNP#HC0 is packaged in an 8-lead 3mm × 3mm DFN with exposed thermal pad (EPAD). The package supports high-power dissipation (θJA = 56°C/W) and requires soldering the EPAD to PCB ground plane for electrical integrity and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pins 1,2) | Regulated output node | Delivers stable output; requires ≥2.2μF MLCC to GND for stability across temperature and load extremes. |
| ADJ (Pin 3) | Feedback reference input | Internally biased at 1.224V; external resistor divider sets VOUT = 1.224V × (1 + R1/R2). |
| NC (Pin 4) | No-connect terminal | Not internally bonded; must remain unconnected per datasheet to avoid parasitic coupling. |
| GND (Pin 5) | Analog and power ground | Primary return path; must be tied directly to system ground and thermally coupled to EPAD. |
| EN (Pin 6) | Enable control input | Active-high logic; 1.35–1.65V threshold ensures robust noise immunity; floating not allowed. |
| VIN (Pins 7,8) | Input power supply | Accepts 2.5–20V; requires local 1μF ceramic capacitor placed adjacent to pins for high-frequency decoupling. |
| EPAD | Exposed thermal pad | Must be soldered to solid copper ground plane; provides primary thermal conduction path and reduces θJA by ~20°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| UVLO with hysteresis | 2.08V rising threshold + 220mV hysteresis prevents oscillation during brown-out conditions. |
| Foldback short-circuit protection | Reduces output current to 240mA under high VIN–VOUT differential, limiting power dissipation during fault. |
| Stable with low-ESR MLCCs | Guaranteed stability with 1μF–200μF X5R/X7R ceramics - eliminates need for tantalum or electrolytic capacitors. |
| Low-noise output | 167μVRMS (10Hz–100kHz) enables clean supply for precision ADCs and RF front-ends. |
| Wide operating junction temperature | Rated for –40°C to +125°C continuous operation - suitable for automotive under-hood and industrial environments. |

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 only; 1A rating; higher IQ (525μA); requires ≥4.7μF output cap. | Not adjustable; unsuitable where variable output or low-IQ battery operation is required. | Select only if fixed 3.3V and higher current headroom outweigh IQ and adjustability trade-offs. |
| Analog Devices ADM7172ACPZ-R7 | 200mA max; 1.8V–5.5V input; lower dropout (175mV @200mA); 25μA IQ; 6-lead LFCSP. | Limited current and input range; better for low-power, low-voltage systems only. | Choose only for space-constrained, sub-200mA designs where 2.5V–20V input support is unnecessary. |
Compared with TPS7A4700RGWR and ADM7172ACPZ-R7, the RAA2142504GNP#HC0 uniquely balances wide input (2.5V–20V), adjustable output (1.224V–18V), 500mA capability, and ultra-low shutdown current (2.4μA) - making it optimal for multi-rail, battery-aware, and industrial field equipment where flexibility and efficiency coexist.

FAQ
What is the minimum output capacitor required for stable operation of the RAA2142504GNP#HC0?
The RAA2142504GNP#HC0 requires a minimum 2.2μF X5R or X7R MLCC capacitor between VOUT and GND for guaranteed stability across –40°C to +125°C, full input range (2.5V–20V), and load extremes (0–500mA). Using smaller values risks oscillation; larger values (up to 200μF) are acceptable and improve transient response.
Does the RAA2142504GNP#HC0 support adjustable output voltage, and how is it configured?
Yes, the RAA2142504GNP#HC0 supports adjustable output from 1.224V to 18V using two external resistors forming a voltage divider from VOUT to ADJ to GND. The ADJ pin is internally referenced to 1.224V, so VOUT = 1.224V × (1 + R1/R2). Shorting ADJ to VOUT yields the minimum 1.224V output.
What protection features does the RAA2142504GNP#HC0 integrate?
The RAA2142504GNP#HC0 integrates input UVLO (2.08V rising, 220mV hysteresis), enable-controlled shutdown, short-circuit current limit with foldback (240–600mA), and over-temperature shutdown (150°C trip, 130°C recovery). All protections operate independently and require no external components.
Can the RAA2142504GNP#HC0 be used with a 1μF input capacitor?
Yes - Renesas specifies a 1μF ceramic capacitor placed as close as possible to the VIN pins, in parallel with a recommended 10μF bulk capacitor. The 1μF capacitor handles high-frequency transients, while the 10μF provides low-frequency energy storage; both are required for optimal line transient response and EMI suppression.
What is the thermal resistance (θJA) of the RAA2142504GNP#HC0 in its DFN package?
The RAA2142504GNP#HC0 in the 8-lead 3mm × 3mm DFN package has a typical junction-to-ambient thermal resistance (θJA) of 56°C/W when mounted on a standard JEDEC high-thermal-conductivity test board with the EPAD soldered to a solid ground plane.
