S-1165B47MC-N7GTFU

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

The S-1165B47MC-N7GTFU is a fixed-output low-dropout CMOS voltage regulator manufactured by ABLIC. It provides a stable 4.7 V output with a maximum continuous current of 200 mA. The device operates within an input voltage range that supports regulation down to a typical dropout voltage of 140 mV, with a maximum specified limit of 200 mV at full load. It features high power supply rejection ratio performance, typically rated at 70 dB. The unit is housed in a compact SOT-23-5 surface-mount package and is designed for operation across an extended industrial temperature range from -40 °C to +85 °C.

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

Verify the complete part number including the suffix N7GTFU to ensure correct packaging and tape-and-reel configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Validate thermal performance requirements against the specified 600 mW power dissipation limit for the SOT-23-5 package under expected operating conditions.

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

Select this component when a fixed 4.7 V rail is required with moderate current capability. Ensure the input voltage exceeds the output by at least the minimum dropout voltage to maintain regulation. Consider the 70 dB PSRR for noise-sensitive applications where linear regulation is preferred over switching converters.
