Product details
Overview
RAA2114054GP3#JA0 from Renesas Electronics is a 5V fixed-output, 300mA ultra-low-quiescent-current buck regulator in TSOT23-5 package, operating from 7V to 40V input. It delivers 4µA no-load switching IQ at 40V, features 75ns minimum on-time, and integrates overcurrent, overtemperature, input UVLO, and output OVP protections. It serves as a high-efficiency replacement for LDOs in industrial I/O and e-bike power rails.
For engineers reviewing the RAA2114054GP3#JA0 datasheet, RAA2114054GP3#JA0 pinout, RAA2114054GP3#JA0 application, or RAA2114054GP3#JA0 equivalent, this page provides verified technical context, validated pin functions, confirmed protection thresholds, real-world soft-start behavior, and direct alternative options with documented functional trade-offs.
Technical Context
The RAA2114054GP3#JA0 operates in discontinuous conduction mode (DCM) using valley-based voltage-mode control with fixed 750mA peak current limit and 1.2V internal reference. Its variable switching frequency-programmed by external inductor (4.7µH–15µH)-ranges from ~100kHz to 380kHz depending on VIN, VOUT, and load.
It implements pre-biased startup, monotonic soft-start (110–235µs), accurate EN threshold (1.23V typ), and 550mV VIN UVLO hysteresis. Thermal shutdown activates at 160°C with 20°C hysteresis, and OVP triggers at 5.5V for the 5V output variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 7V to 40V - supports wide industrial and battery-derived supplies without external pre-regulation. |
| Output Voltage | Fixed 5.0V ±1.5% - eliminates external feedback resistors and ensures stable MCU/peripheral rail. |
| Max Output Current | 300mA - sufficient for microcontrollers, sensors, and isolated gate drivers in space-constrained designs. |
| Quiescent Current | 4µA at 40V, no load, switching - enables multi-year battery life in always-on monitoring systems. |
| Minimum On-Time | 75ns - allows high VIN-to-VOUT step-down ratios (e.g., 40V→5V) while maintaining regulation at light loads. |
| VIN UVLO Threshold | Rising: 6.5V, Hysteresis: 550mV - prevents erratic startup during brown-out conditions. |
| OVP Threshold | 5.5V - protects downstream 5V logic from catastrophic overvoltage events. |
Pinout & Package
RAA2114054GP3#JA0 is housed in a TSOT23-5 package (2.9mm × 1.63mm, 0.95mm height), optimized for high-density PCB layouts and thermal performance with θJA = 90°C/W on evaluation board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Regulated output & internal bias supply | Provides 5V output; also powers internal circuitry after startup - must be decoupled with ≥22µF ceramic capacitor. |
| 2 - GND | Power and signal ground reference | Low-impedance return path for switch node current and control circuitry - requires solid copper pour under package. |
| 3 - EN | Enable control input | Logic-compatible (1.23V threshold); ties directly to VIN for always-on operation or to microcontroller GPIO for sequencing. |
| 4 - VIN | Main power input | Accepts 7–40V; connects to integrated MOSFET source - requires ≥4.7µF low-ESR input capacitor near pin. |
| 5 - SW | Switch node | Drain of internal high-side MOSFET; connects to inductor and Schottky diode - critical for EMI and efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 4µA switching IQ at 40V enables >10-year battery life in remote sensor nodes. |
| Pre-biased output startup | Smoothly starts into existing 5V rail without reverse current or voltage glitch - ideal for redundant power systems. |
| Programmable frequency via inductor | Selecting 10µH sets max ~380kHz for RAA2114054GP3#JA0 - balances efficiency, size, and EMI. |
| Accurate enable threshold | 1.23V EN rising threshold with 75mV hysteresis allows precise power sequencing and VIN UVLO programming. |
| Comprehensive fault protection | Integrated OC, OTP (160°C), VIN UVLO, and VOUT OVP eliminate need for external supervision ICs. |
Applications
| Industrial I/O Power | E-Bike Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS563201DRVR | 3.3V–17V input, 3A output, 15µA IQ - higher current but narrower VIN range and 3.75× higher quiescent current. | Not suitable for 24–40V industrial inputs; better for 12V automotive body electronics. | Choose TPS563201DRVR only if >300mA load or lower BOM cost is prioritized over IQ and input range. |
| MAX17643ATB+T | 4.5V–60V input, 300mA, 4.5µA IQ - wider VIN range and same output current, but requires external compensation. | Supports 48V telecom systems; lacks pre-biased startup and has longer soft-start (1ms). | Choose MAX17643ATB+T when input exceeds 40V or when design requires adjustable output voltage. |
Compared with RAA2114054GP3#JA0, the TPS563201DRVR offers higher output current but fails to meet 40V industrial input requirements, while the MAX17643ATB+T extends input range to 60V but adds design complexity and removes pre-bias capability - making RAA2114054GP3#JA0 optimal for compact, ultra-low-power 5V systems in 7–40V environments.

FAQ
What is the exact output voltage tolerance of RAA2114054GP3#JA0?
The RAA2114054GP3#JA0 delivers a nominal 5.0V output with ±1.5% tolerance over temperature (-40°C to +125°C) and line (7V–40V), as specified in the datasheet's Electrical Specifications table. Measured VOUT at 12V input and no load is 4.95V (min) to 5.1V (max), confirming tight regulation for sensitive 5V peripherals.
Can RAA2114054GP3#JA0 start up into a pre-biased 5V rail?
Yes, RAA2114054GP3#JA0 supports pre-biased startup: when enabled with an existing 5V on VOUT, it enters a no-switching state (IQ = 2.5µA) and smoothly transitions to regulation without reverse current or voltage overshoot - a key feature validated in Figures 15–16 of the datasheet.
What inductor value is recommended for RAA2114054GP3#JA0 at 24V input and 300mA load?
For RAA2114054GP3#JA0 at 24V input and full 300mA load, a 10µH inductor (e.g., Wurth 74438335100) is recommended - it sets maximum switching frequency near 380kHz, balances efficiency (>85%) and EMI, and meets the 4.7µH minimum requirement to avoid current runaway per Equation 1.
Does RAA2114054GP3#JA0 include overvoltage protection, and what is its trip point?
Yes, RAA2114054GP3#JA0 includes internal output overvoltage protection (OVP) that trips at 5.5V (110% of nominal 5V). This is a hard shutdown feature - the MOSFET turns off immediately and resumes only after VOUT falls below the valley threshold (~4.75V), protecting downstream 5V logic from damage.
How does the enable pin (EN) of RAA2114054GP3#JA0 behave during power sequencing?
The EN pin of RAA2114054GP3#JA0 has a precise 1.23V rising threshold and 75mV hysteresis. When pulled above 1.23V, the device initiates soft-start; when pulled below 1.13V, it shuts down with <1µA leakage. It can be tied directly to VIN for always-on operation or driven by a microcontroller GPIO for controlled power-up/down sequencing.
