Product details
Overview
NCP57152MNADJTYG from onsemi is a 1.5 A, adjustable-output, very low-dropout (VLDO) linear regulator in DFN8-4x4 package, delivering stable output voltage from 1.24 V to 13 V with 330 mV typical dropout at 1.5 A load and 1.8 V minimum input voltage - used for FPGA/DSP core power, post-regulation in switching supplies, and battery charger bias rails.
For engineers reviewing the NCP57152MNADJTYG datasheet, pinout, applications, or equivalent options, key selection criteria include its ceramic-capacitor stability, logic-compatible enable/flag pins, thermal shutdown, reverse current protection, and ±2% output voltage accuracy across −40 °C to +125 °C.
Technical Context
The NCP57152MNADJTYG implements an adjustable feedback architecture using external resistor divider (R1/R2) to set output voltage, with ADJ pin held at 1.24 V reference. Its internal error amplifier drives a PMOS pass transistor optimized for fast transient response and low ground current.
It integrates CMOS/TTL-compatible EN input (1.4 V enable threshold), open-collector FLG output (active-low fault indication at 95% VOUT), and protection circuitry including foldback current limiting (2.0–3.0 A), thermal shutdown (>125 °C), and reverse output current blocking up to 6.5 V (VOUT − VIN).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.5 A continuous - supports high-current digital loads like FPGAs without external boost stages. |
| Dropout Voltage | 330 mV typical at 1.5 A - enables operation with minimal VIN–VOUT margin, e.g., 1.8 V input → 1.5 V output. |
| Input Voltage Range | 1.8 V to 13.5 V - compatible with single-cell Li-ion, 3.3 V/5 V/12 V rails, and post-regulation of buck converters. |
| Output Voltage Range | 1.24 V to 13 V adjustable - set via external R1/R2; reference voltage is 1.24 V at ADJ pin. |
| Ground Current | 40–80 mA at 1.5 A load - low quiescent current preserves efficiency in battery-powered systems. |
| Accuracy | ±2% over full load/temperature range - ensures reliable voltage compliance for sensitive logic cores. |
| Thermal Shutdown | Active above +125 °C junction - protects device and PCB during overload or poor heatsinking. |
Pinout & Package
Package: DFN8-4x4 (Case 488AF), Pb-free, exposed thermal pad (EP) connected to GND. 0.8 mm pitch, 8-pin surface-mount with coplanarity-controlled terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference and primary return path for internal circuitry and load current. |
| 2 | VIN | Main input supply rail - powers internal bias and pass element; max 18 V absolute rating. |
| 3 | EN | CMOS/TTL-compatible enable input; logic high ≥1.4 V enables regulator, low ≤0.8 V disables with <5 µA shutdown current. |
| 4,5 | NC | No internal connection - must be left floating or tied to GND per layout best practice. |
| 6 | VOUT | Regulated output node - delivers up to 1.5 A; requires ≥47 µF ceramic capacitor for stability. |
| 7 | ADJ | Feedback input - maintains 1.24 V reference; connects to center tap of R1/R2 divider to set VOUT. |
| 8 | FLG | Open-collector error flag - sinks up to 5 mA when VOUT drops below 95% nominal; requires external pull-up. |
| EP | Exposed Pad | Thermal interface - must be soldered to GND plane for RJA = 75 °C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Fast Transient Response | Stabilizes within microseconds after load steps - critical for FPGA core voltage integrity during burst-mode operation. |
| Ceramic-Capacitor Stability | Guaranteed stable with ≥47 µF X7R/X5R ceramic output cap - eliminates need for bulk electrolytic, saves board space. |
| Reverse Output Current Protection | Blocks reverse current flow when VOUT > VIN (up to 6.5 V differential) - prevents backup battery discharge in dual-rail systems. |
| Logic-Compatible Enable & Flag | EN accepts 0–13.5 V logic signals; FLG provides fail-safe monitoring without level-shifting circuitry. |
| Thermal & Overcurrent Protection | Integrated foldback current limit (2.0–3.0 A) and thermal shutdown - avoids external protection components in compact designs. |
Applications
| FPGA Core Power Supply | Switching Supply Post-Regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC29152-ADJ | Same 1.5 A rating and adjustable output, but 600 mV typical dropout at 1.5 A and 2.5 V min input - higher VIN requirement limits low-voltage use. | Lacks FLG pin and reverse current protection; less suitable for battery-backed or fault-monitoring systems. | Select only if legacy MIC29xx footprint compatibility is required and 1.8 V input operation is not needed. |
| TPS7A8300RGRT | 1.5 A, 1.1 V min input, 200 mV dropout at 1.5 A, but fixed 1.2 V output - no ADJ pin or external resistor network. | Higher PSRR (70 dB @ 100 kHz) and lower noise, but lacks programmability and fault flag functionality. | Prefer when ultra-low noise is critical and output voltage is fixed; avoid when adjustable VOUT or FLG monitoring is required. |
Compared with MIC29152-ADJ and TPS7A8300RGRT, the NCP57152MNADJTYG uniquely combines 1.8 V minimum input, 330 mV dropout, adjustable output, and integrated error flag - making it optimal for space-constrained, multi-rail systems requiring both flexibility and fault visibility.

FAQ
What is the maximum input voltage rating for the NCP57152MNADJTYG?
The NCP57152MNADJTYG has an absolute maximum input voltage (VIN) rating of 18 V, though recommended operating range is 1.8 V to 13.5 V. Exceeding 13.5 V may compromise long-term reliability or trigger internal protection circuits, even if within absolute max limits. Always refer to the Recommended Operating Conditions table in the official datasheet for safe design margins.
Does the NCP57152MNADJTYG require an external capacitor on the ADJ pin?
No, the NCP57152MNADJTYG does not require an external capacitor on the ADJ pin. The ADJ pin functions as a high-impedance feedback node referenced to 1.24 V; stability is ensured solely by the output capacitor (≥47 µF ceramic). Adding capacitance to ADJ would disrupt regulation and is not supported by the device architecture or datasheet recommendations.
Can the NCP57152MNADJTYG operate with a 1.5 V input supply?
No, the NCP57152MNADJTYG cannot operate with a 1.5 V input supply. Its minimum recommended input voltage is 1.8 V to deliver full 1.5 A output current. At 1.5 V input, the device will not regulate - output voltage collapses due to insufficient headroom, especially for outputs ≥1.24 V. Designers must ensure VIN ≥ VOUT + dropout voltage (e.g., ≥1.57 V for 1.24 V output), but 1.8 V is the guaranteed functional floor.
Is the NCP57152MNADJTYG pin-compatible with the NCP57152DSADJR4G?
No, the NCP57152MNADJTYG (DFN8-4x4) is not pin-compatible with the NCP57152DSADJR4G (D2PAK-5). They share identical electrical specifications and functional pin definitions (EN, VIN, GND, VOUT, ADJ, FLG), but differ in physical layout: DFN8 has 8 pins including NC and EP; D2PAK-5 has 5 pins plus tab. PCB layout, thermal pad routing, and footprint are incompatible - direct replacement requires board redesign.
What is the purpose of the FLG pin on the NCP57152MNADJTYG?
The FLG pin on the NCP57152MNADJTYG is an open-collector error flag that actively pulls low when output voltage falls below 95% of nominal (e.g., <2.375 V for 2.5 V setting). It sinks up to 5 mA and requires an external pull-up resistor. This enables real-time fault detection for system-level monitoring - such as triggering MCU interrupts or disabling downstream circuitry - without additional supervisory ICs.
