NCV8570SN25T1G

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The NCV8570SN25T1G is a fixed-output low-dropout (LDO) voltage regulator from onsemi, delivering a precise 2.5 V output with a maximum continuous current of 200 mA. Designed for ultra-low noise RF applications, it features a typical power supply rejection ratio (PSRR) of 80 dB and a low dropout voltage of 120 mV at full load. The device operates within an input voltage range supporting the specified output, maintaining stability across a wide temperature range from -40°C to +125°C. It incorporates a shutdown feature to minimize quiescent current to 75 µA in standby mode. Packaged in a compact SOT-23-5 surface-mount case, this component ensures high line and load regulation for sensitive analog circuits.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this LDO when low noise and high PSRR are critical for signal integrity in RF sections. Ensure the input voltage remains above the minimum requirement while accounting for dropout voltage under maximum load. Consider the SOT-23-5 package size constraints and thermal dissipation capabilities relative to the expected power loss in the application.
