Product details
Overview
NCV59301DS25R4G from onsemi is an automotive-grade, 2.5 V fixed-output, 3.0 A very low-dropout (VLDO) linear regulator in D2PAK-5 package with enable and error flag pins. It delivers ≤300 mV typical dropout at 3.0 A load, supports 2.24–13.5 V input range, features reverse output current protection, thermal shutdown, and ±2.5% output voltage accuracy across –40°C to +125°C for FPGA/DSP point-of-load regulation.
For engineers reviewing the NCV59301DS25R4G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout performance at full load, AEC-Q100 qualification, open-collector FLG behavior under undervoltage, and compatibility with ceramic output capacitors ≥47 µF.
Technical Context
The NCV59301DS25R4G implements a PMOS pass transistor architecture enabling fast transient response and stable operation with low-ESR ceramic capacitors. Its internal error amplifier monitors VOUT against a precision bandgap reference and drives the pass element to maintain regulation within ±2.5% over line, load, and temperature.
Logic-compatible EN pin enables TTL/CMOS control with 1.8 V high-threshold and 0.8 V low-threshold; FLG pin asserts low when VOUT falls below 95% of nominal (2.375 V), with 2% hysteresis and 250 µA sink capability. Protection includes foldback current limiting, thermal shutdown at +125°C junction, and reverse current blocking up to 6.5 V (VOUT–VIN).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2.5% over –40°C to +125°C; ensures stable core supply for 2.5 V FPGA I/O banks. |
| Max Output Current | 3.0 A continuous; supports high-current digital loads without external current boosting. |
| Dropout Voltage | 300 mV typical at 3.0 A; allows operation with VIN as low as 2.8 V while maintaining regulation. |
| Ground Current | 60–120 mA at 3.0 A load; minimizes wasted power in high-efficiency systems. |
| PSRR | ≥60 dB at 1 kHz (COUT = 47 µF ceramic); suppresses switching noise from upstream DC/DC converters. |
| Enable Threshold | EN high ≥1.8 V, low ≤0.8 V; interfaces directly with 1.8 V/3.3 V logic without level-shifting. |
| Error Flag Threshold | Active-low at 95% VOUT (2.375 V) with 2% hysteresis; provides clean fault signaling for system monitoring. |
Pinout & Package
D2PAK-5 package (Case 936A) with exposed tab thermally and electrically connected to GND; 5-pin surface-mount outline optimized for high-power dissipation and PCB heat spreading.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Enable input | CMOS/TTL-compatible control: high ≥1.8 V enables regulation; low ≤0.8 V places device in ultra-low-IQ shutdown (<5 µA). |
| 2 - VIN | Input supply | Accepts 2.24–13.5 V; supplies internal circuitry and output load current; max rating 18 V. |
| 3 - GND | Ground reference | Common return for input, output, and internal circuits; tab is internally bonded to this pin. |
| 4 - VOUT | Regulated output | Delivers stable 2.5 V ±2.5% to load; requires ≥47 µF ceramic capacitor for stability and transient response. |
| 5 - FLG | Error flag output | Open-collector output sinking up to 250 µA; pulls low when VOUT < 2.375 V; requires external pull-up resistor. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV59300DS25R4G | D2PAK-3 package (3-pin), no EN/FLG pins; same electrical specs except missing logic control and fault reporting. | Suitable only for always-on, non-monitored applications where board space is constrained and diagnostics are unnecessary. | Select NCV59300DS25R4G if footprint reduction and absence of enable/flag functionality are acceptable trade-offs. |
| TPS7A8300RGRT | 3 A, 2.5 V LDO with 115 mV dropout at 3 A; higher PSRR (70 dB @ 1 kHz); requires minimum 22 µF ceramic output cap. | Targeted at ultra-low-noise RF and high-speed ADC applications; not AEC-Q100 qualified. | Choose TPS7A8300RGRT only for non-automotive, noise-sensitive designs where lowest possible dropout and highest PSRR are mandatory. |
Compared with NCV59301DS25R4G, NCV59300DS25R4G eliminates diagnostic capability and control flexibility but saves PCB area, while TPS7A8300RGRT improves noise rejection and dropout at the cost of automotive qualification and increased design complexity.

FAQ
What is the maximum input voltage rating for the NCV59301DS25R4G?
The NCV59301DS25R4G has an absolute maximum input voltage rating of 18 V, but its recommended operating range is 2.24 V to 13.5 V. Operation above 13.5 V is not guaranteed and may compromise long-term reliability or trigger internal protection circuits. The 18 V rating defines the stress limit beyond which permanent damage may occur.
Does the NCV59301DS25R4G require an external pull-up resistor on the FLG pin?
Yes, the NCV59301DS25R4G FLG pin is an open-collector output and requires an external pull-up resistor to a valid logic-high voltage (e.g., VIN or VOUT). Typical values range from 10 kΩ to 100 kΩ. Without this resistor, the FLG signal cannot assert a defined high state during normal operation, rendering fault detection nonfunctional.
Can the NCV59301DS25R4G be used with tantalum or aluminum electrolytic output capacitors?
No-the NCV59301DS25R4G is specifically characterized and guaranteed stable only with ceramic output capacitors ≥47 µF. Tantalum or aluminum electrolytic capacitors introduce ESR and aging effects that can destabilize the control loop, leading to oscillation or poor transient response. The datasheet explicitly states ceramic capacitor compatibility as a design requirement.
What is the shutdown current consumption of the NCV59301DS25R4G when EN is low?
When the EN pin is held ≤0.5 V, the NCV59301DS25R4G enters shutdown mode with ground pin current ≤5 µA. This ultra-low quiescent current enables battery-backed systems to maintain extended standby time without significant drain, making it suitable for automotive infotainment modules with wake-on-LIN/CAN requirements.
Is the NCV59301DS25R4G pin-compatible with the NCP59301DS25R4G?
Yes-the NCV59301DS25R4G and NCP59301DS25R4G share identical D2PAK-5 pinout, electrical specifications, and thermal characteristics. The only difference is automotive qualification: NCV devices undergo additional AEC-Q100 stress testing and PPAP documentation, while NCP versions target commercial/industrial use. Both are drop-in replacements in hardware layout.
