LMR36502P3RPER

Voltage Regulators - DC DC Switching Regulators Overview

The LMR36502P3RPER is a synchronous step-down DC/DC converter manufactured by Texas Instruments. It operates with an input voltage range of 3 V to 65 V and provides a fixed output voltage of 3.3 V at a maximum output current of 150 mA. The device features a quiescent current of 1 uA and an operating supply current of 6.5 uA. It supports adjustable switching frequencies from 200 kHz to 2.2 MHz. The component is housed in a VQFN-HR-9 package, rated for operation between -40°C and +150°C, and includes shutdown functionality.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Battery-powered equipment needing high efficiency

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix P3RPER to confirm the fixed 3.3 V output configuration and tape-and-reel packaging format. Ensure compatibility with the VQFN-HR-9 footprint during PCB layout. Confirm moisture sensitivity level handling requirements prior to assembly. Cross-reference the datasheet for thermal performance expectations under expected load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 3.3 V output is required within the LMR36502 family. Compare against LMR36502PS5RPER if a 5 V output is needed instead. Consider the LMR36502F3RPER if an adjustable output voltage range is preferred over a fixed value. Evaluate the 150 mA current limit against peak load demands to ensure adequate headroom.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LMR36502 series of ultra-small synchronous buck converters from Texas Instruments. The series offers various output configurations including fixed voltages and adjustable options. The P3RPER designation specifically identifies the 3.3 V fixed output variant packaged in reels for automated surface-mount assembly processes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR36502PS5RPER serves as a direct alternative for designs requiring a 5 V output instead of 3.3 V. LMR36502F3RPER is suitable if an adjustable output voltage is desired rather than a fixed regulation point.
