Product details
Overview
RAA2114034GP3#JA0 from Renesas Electronics is a 300mA, ultra-low-quiescent-current (4µA at 40V no-load switching) synchronous buck regulator in TSOT23-5 package, delivering fixed 3.3V output across 7–40V input range. It integrates high-side MOSFET (rDS(ON) = 1.0Ω), supports pre-biased start-up, and provides comprehensive protection including VIN UVLO (6.5V threshold), OVP (3.63V), OTP (160°C), and overcurrent limiting (750mA peak).
For engineers reviewing the RAA2114034GP3#JA0 datasheet, RAA2114034GP3#JA0 pinout, RAA2114034GP3#JA0 application, or RAA2114034GP3#JA0 equivalent, key selection considerations include its 75ns minimum on-time for high-VIN/low-VOUT operation, variable-frequency control via external inductor (4.7–15µH), and suitability for space-constrained industrial and e-bike power rails requiring <5µA standby current.
Technical Context
The RAA2114034GP3#JA0 operates in discontinuous conduction mode (DCM) using valley-based voltage-mode control with fixed 750mA peak current limit and zero-current detection. Its switching frequency varies with load, input voltage, and inductor value-e.g., ~210kHz max with 15µH at full load-and it maintains regulation down to 0mA output current.
Startup behavior includes monotonic, pre-bias-capable soft-start (110–135µs no-load), accurate EN threshold (1.23V typ), and UVLO hysteresis (550mV). The IC draws only 2.5µA in shutdown (EN = 0V) and 0.1µA in true shutdown state, enabling long battery life in always-on systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 7V to 40V - supports wide-range industrial and e-bike battery inputs without pre-regulation. |
| Output Voltage | Fixed 3.3V ±3% - eliminates external feedback resistors and simplifies layout for standard logic rail generation. |
| Max Output Current | 300mA - sufficient for microcontrollers, sensors, and I/O peripherals in embedded systems. |
| Quiescent Current | 4µA at 40V, no load, switching - enables >10-year battery life in low-duty-cycle remote sensors. |
| Min On-Time | 75ns - allows stable 3.3V output from 40V input (12:1 step-down ratio) without pulse-skipping artifacts. |
| Protection Features | VIN UVLO (6.5V), OVP (3.63V), OTP (160°C), OC limit (750mA) - ensures robust operation under fault conditions without external circuitry. |
| Enable Threshold | 1.23V typical with 75mV hysteresis - permits direct connection to 3.3V logic or precise UVLO programming via resistor divider. |
Pinout & Package
RAA2114034GP3#JA0 is housed in a compact TSOT23-5 package (2.9mm × 1.63mm, 0.95mm height), optimized for high-density PCB layouts and thermal performance (θJA = 90°C/W on evaluation board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Regulated output & internal bias supply | Provides 3.3V output and powers internal circuitry post-startup; must be decoupled with ≥22µF ceramic capacitor. |
| 2 - GND | Power and signal reference ground | Low-impedance return path for switch node current and feedback; requires solid thermal pad connection to PCB ground plane. |
| 3 - EN | Enable control input | Logic-compatible input (1.23V threshold); tie to VIN for always-on operation or drive with MCU GPIO for dynamic power gating. |
| 4 - VIN | Main power input | Accepts 7–40V; connects to integrated high-side MOSFET source and internal LDO; requires ≥4.7µF input capacitance. |
| 5 - SW | Switch node | Drain of internal high-side MOSFET; connects to inductor and Schottky diode; critical for EMI and efficiency-requires short, low-inductance routing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 4µA quiescent current at 40V enables multi-year operation from coin-cell or energy-harvesting sources. |
| Pre-biased start-up | Starts cleanly into existing 3.3V rail without reverse current or output glitch-ideal for redundant power systems. |
| Variable frequency control | Switching frequency scales with load and inductor value (4.7–15µH), eliminating need for external frequency setting components. |
| Monotonic soft-start | 110–135µs no-load ramp time prevents inrush current and avoids brown-out in downstream logic during power-up. |
| Integrated MOSFET | 1.0Ω rDS(ON) high-side switch reduces BOM count and improves efficiency vs. external-FET solutions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63036YFFR | 3.3V fixed output, 400mA, 1.5µA IQ, but 3–17V input range - lacks high-VIN capability. | Suitable for USB-powered or low-VIN IoT hubs; cannot replace RAA2114034GP3#JA0 in 24–40V industrial rails. | Select when input stays below 17V and sub-2µA IQ is critical; verify thermal performance at 400mA continuous load. |
| MAX17552ATP+T | Adjustable output (0.9–5V), 400mA, 10µA IQ, 4.5–42V input - higher IQ and requires external feedback resistors. | Offers flexibility for multi-rail designs but increases BOM and layout complexity vs. RAA2114034GP3#JA0's fixed 3.3V. | Choose when adjustable VOUT or higher current is needed; accept 2.5× higher IQ and added component count. |
Compared with TPS63036YFFR and MAX17552ATP+T, RAA2114034GP3#JA0 uniquely combines 40V input support, 4µA IQ, fixed 3.3V output, and TSOT23-5 footprint-making it optimal for space- and power-constrained 24–40V industrial and mobility applications where simplicity and ultra-low standby loss are mandatory.

FAQ
What is the maximum input voltage rating for RAA2114034GP3#JA0?
The absolute maximum input voltage for RAA2114034GP3#JA0 is 42V, with recommended operation from 7V to 40V. Exceeding 42V risks permanent damage. The device incorporates VIN UVLO with 6.5V turn-on and 6.0V turn-off thresholds to ensure safe startup and shutdown across this range. Always use appropriate input filtering and transient protection when operating near the 40V upper limit.
Does RAA2114034GP3#JA0 support pre-biased output startup?
Yes, RAA2114034GP3#JA0 fully supports pre-biased output startup. When enabled with an existing 3.3V on the VOUT pin, it enters regulation smoothly without reverse current or output voltage overshoot. This feature is confirmed in Figures 15–16 of the datasheet and enables use in redundant power architectures and hot-swap battery systems without additional external circuitry.
What inductor value is recommended for RAA2114034GP3#JA0 in a typical 24V-to-3.3V application?
For a 24V-to-3.3V application at 300mA, Renesas recommends a 15µH inductor (e.g., Wurth 74438335150) to achieve ~210kHz maximum switching frequency and optimal efficiency. Lower values (e.g., 10µH) increase frequency and ripple; values below 4.7µH risk exceeding the 750mA peak current limit and violating the 75ns minimum on-time constraint. Inductor DCR should be ≤720mΩ to maintain thermal performance.
How does the enable pin (EN) function on RAA2114034GP3#JA0?
The EN pin on RAA2114034GP3#JA0 has a precise 1.23V typical turn-on threshold with 75mV hysteresis. It is high-voltage tolerant (rated to VIN + 0.3V), allowing direct connection to VIN for always-on operation or to a 3.3V/5V logic signal. When pulled low (<1.13V), the device enters shutdown with only 0.1µA current draw. No external pull-up is required, but floating EN must be avoided.
What protections are built into RAA2114034GP3#JA0?
RAA2114034GP3#JA0 integrates five core protections: input undervoltage lockout (UVLO), output overvoltage protection (OVP at 3.63V), overcurrent limiting (750mA peak), overtemperature shutdown (160°C), and short-circuit recovery. All are autonomous and require no external components. Fault conditions trigger automatic recovery after removal-e.g., OTP resumes via soft-start once junction temperature drops below 140°C.
