Product details
Overview
NCP715SN12T1G from onsemi is a 50 mA fixed-output (1.2 V) low-dropout linear voltage regulator with ultra-low quiescent current (4.7 µA max over full load and temperature), wide input voltage range (2.5 V to 24 V), ±2% output accuracy, and integrated thermal shutdown and current limiting. It delivers stable power to battery-powered sensors and low-power microcontrollers in space-constrained industrial IoT nodes.
For engineers reviewing the NCP715SN12T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 50 mA (≤450 mV), PSRR of 60 dB at 100 kHz, output noise of 65 µVRMS (200 Hz–100 kHz), thermal shutdown threshold (170 °C), and TSOP-5 package compatibility with high-density PCB layouts.
Technical Context
The NCP715SN12T1G implements a bandgap-referenced error amplifier driving a PMOS pass transistor, enabling low dropout and ultra-low ground current. Its internal UVLO ensures startup only above 2.5 V, and the current-limiting circuit protects against short-circuit faults without external components.
Thermal shutdown activates at 170 °C with 15 °C hysteresis, and stability is guaranteed with ≥0.47 µF ceramic output capacitance-no ESR requirement. The device operates across −40 °C to +125 °C ambient, with junction temperature limited to 150 °C maximum.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1202E/TT | 250 mA rated, 1.8 µA IQ, SOT-23-5 package, 600 mV dropout at 250 mA | Higher current capability but larger dropout and different pinout; not drop-in compatible | Select when >50 mA load or lower IQ is critical; requires PCB layout change |

FAQ
What is the maximum input voltage rating for the NCP715SN12T1G?
The NCP715SN12T1G has an absolute maximum input voltage rating of 24 V, with recommended operating range from 2.5 V to 24 V. Exceeding 24 V risks permanent damage per the Absolute Maximum Ratings table. For reliable operation, maintain input within this range and ensure proper input decoupling with ≥0.1 µF ceramic capacitor.
Does the NCP715SN12T1G require a minimum ESR output capacitor?
No, the NCP715SN12T1G does not require minimum ESR for stability. It is explicitly designed to remain stable with standard X5R or X7R ceramic capacitors ranging from 0.47 µF to 10 µF-eliminating the need for tantalum or aluminum electrolytic capacitors and simplifying BOM selection.
What is the thermal shutdown behavior of the NCP715SN12T1G?
The NCP715SN12T1G activates thermal shutdown at 170 °C junction temperature and remains latched off until junction temperature falls by 15 °C (hysteresis), resuming regulation at ~155 °C. This protects the device during sustained overload or inadequate PCB heatsinking without requiring external reset circuitry.
Can the NCP715SN12T1G be used with a 3.3 V input to deliver 1.2 V at 50 mA?
Yes-the NCP715SN12T1G supports 3.3 V input for 1.2 V output at 50 mA. Dropout voltage is characterized at ≤450 mV under these conditions (VIN = 3.5 V), ensuring sufficient headroom. Efficiency is ~36%, appropriate for low-power applications where simplicity and low noise outweigh efficiency concerns.
How does the NCP715SN12T1G compare to other 1.2 V LDOs in terms of noise performance?
The NCP715SN12T1G delivers 65 µVRMS output noise (200 Hz–100 kHz), measured with 10 µF output capacitance. This is among the lowest in its class for 50 mA LDOs-superior to typical competitors like the AP2210K-12 (120 µVRMS)-making it ideal for precision analog circuits powered from the same rail.
