MCP1703A-1802E/DB

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

The MCP1703A-1802E/DB is a fixed-output low dropout linear regulator manufactured by Microchip Technology. It provides a regulated 1.8 V output with a maximum continuous current of 200 mA, as the output voltage is below the 2.5 V threshold for 250 mA capability. The device operates within an input voltage range of 2.7 V to 16.0 V and features a typical quiescent current of 2.0 µA. It utilizes a SOT-223-3 surface-mount package and maintains stability with ceramic output capacitance between 1.0 µF and 22 µF.

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

Low quiescent current consumption suitable for battery-powered applications
High input voltage operating range up to 16.0 V
Stable operation with small ceramic output capacitors
Integrated short-circuit and overtemperature protection

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

Verify the specific suffix E/DB corresponds to the SOT-223-3 package configuration required for your PCB layout. Confirm that the 1.8 V fixed output aligns with system voltage requirements, noting the reduced 200 mA current limit for outputs under 2.5 V. Ensure compliance with RoHS directives if applicable to your manufacturing standards.

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

Select this component when a stable 1.8 V rail is needed from inputs ranging up to 16 V. The SOT-223-3 package offers better thermal performance than smaller alternatives. Consider the 200 mA current limitation for loads exceeding this threshold. Verify that the application environment stays within the -40°C to +125°C junction temperature range.

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

This part belongs to the MCP1703A family of micropower LDO regulators. It serves as an improved version of the original MCP1703, offering faster startup times and reduced ground current during dropout conditions. The family supports various fixed output voltages and multiple package options including SOT-23A and DFN.
