NCP170BMX135TCG

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

The NCP170BMX135TCG is a fixed-output low-dropout (LDO) voltage regulator manufactured by onsemi. It provides a stable 1.35 V output with a maximum load current of 150 mA. The device operates within an input voltage range of 2.2 V to 5.5 V and features an ultra-low quiescent current of 500 nA. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 57 dB, a line regulation of 0.05 %/V, and a load regulation of 1 mV. The dropout voltage is specified at 170 mV. It is housed in a compact XDFN-4 surface-mount package and supports an operating temperature range from -40 °C to +85 °C.
