LP5951MF-2.0/NOPB

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

The LP5951MF-2.0/NOPB is a micropower, low-dropout (LDO) CMOS voltage regulator manufactured by Texas Instruments. It provides a fixed positive output of 2.0 V with a maximum load current of 150 mA. The device operates within an input voltage range of 1.8 V to 5.5 V and features a typical quiescent current of 55 µA. It offers a dropout voltage of 200 mV at full load and achieves a typical power supply rejection ratio (PSRR) of 60 dB. The component is housed in a SOT-23-5 package and supports operation across a temperature range of -40°C to +125°C.

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

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance as per Texas Instruments standards. Confirm the 'MF' package code corresponds to the SOT-23-5 footprint required for your PCB layout. Ensure the fixed 2.0 V output matches your circuit's voltage rail requirements before procurement.

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

Select this component when a fixed 2.0 V output is required with minimal board space due to the SOT-23-5 package. It is suitable for applications prioritizing low static current consumption and high PSRR. Consider the 150 mA current limit and 5.5 V maximum input voltage to ensure compatibility with the system's power source and load demands.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the LP5951 series of micropower LDO regulators from Texas Instruments. The series includes various fixed output voltages and package options such as SC70-5.
