RP173N361D-TR-FE

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

The RP173N361D-TR-FE is a low dropout regulator from the Nisshinbo RP173N series, housed in an SOT-23-5 package. It provides a fixed 3.6 V output with a maximum current of 150 mA. The device supports input voltages up to 11 V and operates within a temperature range of -40°C to +85°C. Key electrical characteristics include a typical power supply rejection ratio of 30 dB and a dropout voltage of 610 mV. It features ultra-low quiescent current of 2 µA and includes reverse current protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated reverse current protection prevents backflow when input voltage drops below output voltage.
• Ultra-low operating current minimizes power consumption in battery-powered applications.
• Fixed output voltage ensures stable regulation without external feedback components.

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

• Battery-operated portable electronic devices
