Product details
Overview
NCP4620HSN15T1G from onsemi is a 150 mA, 1.5 V fixed-output CMOS low-dropout linear regulator in SOT-23-5 package, operating from 2.6 V to 10 V input, with ±1.0% output voltage accuracy, 165 mV dropout at 100 mA (3.3 V version), and chip enable functionality. It delivers stable power to portable battery-powered systems requiring low quiescent current and ceramic capacitor compatibility.
For engineers reviewing the NCP4620HSN15T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout performance at 150 mA load, thermal shutdown threshold (165°C), CE pin logic high threshold (1.7 V), and stability with 1 µF ceramic output capacitance without ESR requirements.
Technical Context
The NCP4620HSN15T1G implements a CMOS-based pass transistor architecture with internal bandgap reference and error amplifier, enabling tight line regulation (0.02%/V typ) and low temperature drift (±80 ppm/°C). Its CE pin controls an internal NMOS switch that disables the regulator and reduces supply current to ≤1.0 µA.
Unlike the auto-discharge D-version, the H-version lacks the VOUT-to-GND discharge transistor - resulting in slower output decay during disable but lower standby current and simpler biasing. The device features fold-back current limiting and thermal shutdown with hysteresis (110°C release).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±1.0% over −40°C to +85°C - ensures stable core voltage for low-power microcontrollers and sensors. |
| Max Output Current | 150 mA continuous - supports moderate-load applications like camera modules and STB subsystems. |
| Dropout Voltage | 250 mV at 150 mA (1.5 V version) - enables operation from two Li-ion cells (min ~2.6 V) with margin. |
| Quiescent Current | 23 µA typical - extends battery life in always-on or low-duty-cycle portable devices. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| CE Threshold | VCEH = 1.7 V min - compatible with 1.8 V and 3.3 V GPIOs without level-shifting. |
| Thermal Shutdown | Triggers at 165°C, releases at 110°C - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
SOT-23-5 package (Case 1212), 2.7 mm × 2.5 mm footprint, 1.3 mm height, Pb-free, RoHS-compliant. Thermal resistance RJA = 238°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input supply | Accepts 2.6–10 V; requires local 1 µF ceramic decoupling to minimize line transients. |
| 2 (GND) | Ground reference | Common return path for input/output currents; must be low-impedance and tied to power plane. |
| 3 (CE) | Chip enable input | Active-high logic control; internal pull-down ensures default-off state if left floating. |
| 4 (NC) | No connection | Not bonded; must remain unconnected - no routing or soldering allowed. |
| 5 (VOUT) | Regulated output | Delivers 1.5 V ±1.0%; stable with ≥1 µF ceramic capacitor; no ESR requirement. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 250 mV at full 150 mA load for 1.5 V output - enables efficient use of depleted battery voltage. |
| Ceramic capacitor stability | Stable with 1 µF X5R/X7R ceramic output cap - eliminates need for costly tantalum or aluminum electrolytics. |
| Enable-controlled shutdown | Reduces total supply current to ≤1.0 µA when CE = low - critical for ultra-low-power sleep modes. |
| High PSRR | 70 dB at 1 kHz - maintains clean 1.5 V rail despite noisy mixed-signal board environments. |
| Thermal protection with hysteresis | Shuts down at 165°C, resumes at 110°C - prevents thermal runaway while allowing recovery after transient overload. |
Applications
| Battery-Powered Cameras | Set-Top Box Subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/TT | 150 mA, 1.5 V, 6 µA IQ, SC-70-5 - lower quiescent current but higher dropout (330 mV @ 150 mA). | Preferred for multi-year battery life in wake-on-event IoT nodes; less suitable for high-current bursts. | Select when ultra-low IQ dominates over dropout or thermal performance. |
| Torex XC6206P152MR-G | 150 mA, 1.5 V, 1.0 µA IQ, SOT-23-5 - near-zero standby current but only 80 mA guaranteed output and no CE pin. | Used in space-constrained wearables where CE control is unnecessary and peak load is <80 mA. | Choose when minimal footprint and lowest possible IQ are mandatory, and enable control is handled externally. |
Compared with MCP1700T-1502E/TT and XC6206P152MR-G, the NCP4620HSN15T1G offers superior thermal robustness (165°C shutdown), tighter output accuracy (±1.0%), and integrated CE logic - making it optimal for industrial and consumer applications demanding reliability under variable load and temperature.

FAQ
What is the maximum input voltage rating for the NCP4620HSN15T1G?
The absolute maximum input voltage for the NCP4620HSN15T1G is 12.0 V, but the recommended operating input voltage range is 2.6 V to 10.0 V. Exceeding 10 V may degrade long-term reliability or trigger overvoltage stress not covered by standard qualification testing. Operation within the 2.6–10 V range ensures full specification compliance across temperature and load conditions for the NCP4620HSN15T1G.
Does the NCP4620HSN15T1G require an external resistor network to set output voltage?
No, the NCP4620HSN15T1G is a fixed-output regulator with factory-trimmed 1.5 V output - no external resistors are needed or supported. The "H" suffix denotes the standard version without auto-discharge, and the "15" in the part number explicitly indicates the 1.5 V nominal output. This simplifies layout and eliminates resistor tolerance errors affecting final voltage accuracy for the NCP4620HSN15T1G.
Can the NCP4620HSN15T1G operate stably with a 0.47 µF ceramic output capacitor?
Yes, the NCP4620HSN15T1G is specified to be stable with output capacitors as low as 0.47 µF ceramic (per Electrical Characteristics table), though 1 µF is recommended for optimal transient response and PSRR. Stability is maintained across X5R/X7R dielectrics without ESR requirements - unlike older bipolar LDOs - ensuring robust performance for the NCP4620HSN15T1G in miniaturized layouts.
What is the function of Pin 4 (NC) on the NCP4620HSN15T1G SOT-23-5 package?
Pin 4 on the NCP4620HSN15T1G is marked NC (No Connection) and is not internally bonded - it must remain unconnected on the PCB. Routing traces to or placing solder on this pin risks shorting adjacent pins or compromising thermal performance. The NC designation is confirmed in the official Pin Function Description table on page 2 of the NCP4620 datasheet, and applies strictly to the NCP4620HSN15T1G variant.
How does the thermal shutdown behavior of the NCP4620HSN15T1G protect the device during overload?
The NCP4620HSN15T1G activates thermal shutdown at 165°C junction temperature and remains latched off until junction temperature falls to 110°C (55°C hysteresis). During shutdown, output is disabled and quiescent current drops to ≤1.0 µA. This prevents cumulative thermal damage during sustained overload or inadequate heatsinking, and allows safe automatic recovery once ambient conditions improve - a key reliability feature of the NCP4620HSN15T1G.
