Product details
Overview
NCP715SN25T1G from onsemi is a 2.5 V fixed-output, 50 mA ultra-low quiescent current LDO linear voltage regulator in TSOP-5 package. It operates from 3.5 V to 24 V input, delivers ±2% output accuracy over load/line/temperature, features 260 mV typical dropout at 50 mA, and integrates thermal shutdown and current limiting. It powers low-power microcontrollers in battery-operated IoT sensors.
For engineers reviewing the NCP715SN25T1G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low IQ (4.2 µA max at 50 mA), wide VIN range (3.5–24 V), PSRR (60 dB @ 100 kHz), noise performance (115 µVRMS), and TSOP-5 thermal resistance (250 °C/W).
Technical Context
The NCP715SN25T1G uses a PMOS pass transistor architecture enabling low dropout and near-zero load-dependent quiescent current. Its bandgap reference and error amplifier deliver stable 2.5 V regulation across −40°C to +125°C ambient with <±2% total error.
Protection circuitry includes foldback current limiting that activates at ~100 mA and thermal shutdown triggered at 170°C junction temperature with 15°C hysteresis. The device requires no minimum ESR output capacitor and remains stable with 0.47 µF ceramic capacitors.
Key Specifications

FAQ
What is the maximum input voltage rating for the NCP715SN25T1G?
The NCP715SN25T1G has an absolute maximum input voltage rating of 24 V. Its recommended operating input voltage range is 3.5 V to 24 V for the 2.5 V output version. Operation above 24 V risks permanent damage per Absolute Maximum Ratings table on page 3 of the datasheet.
Does the NCP715SN25T1G require an external output capacitor, and what value is recommended?
Yes, the NCP715SN25T1G requires an external ceramic output capacitor for stability. The datasheet specifies a minimum of 0.47 µF (X5R or X7R dielectric), with values up to 10 µF supported. Larger capacitance improves line transient response without compromising stability.
What is the thermal shutdown behavior of the NCP715SN25T1G?
The NCP715SN25T1G activates thermal shutdown at 170°C junction temperature and remains latched off until junction temperature falls by 15°C (hysteresis). Recovery is automatic once temperature drops below 155°C. This protects against sustained overload or poor heatsinking.
Can the NCP715SN25T1G be used with a 3.3 V input supply?
No - the NCP715SN25T1G requires a minimum input voltage of 3.5 V for guaranteed 2.5 V regulation across all loads and temperatures. At 3.3 V input, dropout margin is insufficient; output will drop below specification. Use only within 3.5–24 V operating range.
How does the quiescent current of the NCP715SN25T1G vary with load and temperature?
The NCP715SN25T1G maintains ultra-low quiescent current: ≤4.2 µA at 50 mA load and −40°C to +85°C ambient, rising to ≤5.8 µA at VIN = 24 V. Figure 19–22 in the datasheet confirm minimal variation across temperature and load, enabling predictable battery-life calculations.
