MCP1700-1302E/TO

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

The MCP1700-1302E/TO is a fixed-output CMOS low dropout (LDO) voltage regulator manufactured by Microchip Technology. It provides a nominal output voltage of 1.3V with a maximum load current capability of 200 mA, as the output voltage is below the 2.5V threshold for 250 mA operation. The device operates within an input voltage range of 2.3V to 6.0V and features a typical quiescent current of 1.6 µA. It utilizes a TO-92 package with three pins.

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

Verify the specific suffix 'E/TO' corresponds to the TO-92 through-hole package variant when sourcing. Confirm that the 1.3V output rating aligns with the 200 mA maximum current limit specified for outputs under 2.5V in the official datasheet. Ensure compliance with RoHS standards as indicated by the manufacturer's documentation.

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

Select this component for applications requiring a stable 1.3V rail from single-cell Li-Ion or multi-cell alkaline batteries. Consider the 200 mA current limit for loads exceeding standard sensor requirements. Evaluate thermal dissipation based on the TO-92 package thermal resistance if operating near maximum load currents.
