MCP1700T in Microchip MCP1700 / MCP1825 LDO Family
The MCP1700T family by Microchip Technology consists of low dropout (LDO) linear regulators characterized by an extremely low quiescent current of 1.6 µA. Designed for CMOS-level efficiency, these regulators support input voltages up to 6.0V and provide a stable output of up to 250mA. They are engineered to maintain a low dropout voltage (typically 178mV at full load), making them ideal for applications where battery life and board space are critical constraints in power management circuitry.

The MCP1700T sub-family variants are distinguished primarily by their fixed output voltage ratings, ranging from 1.2V to 5.0V, and their physical packaging. The TT suffix denotes the SOT-23-3 package, while the MB suffix indicates the SOT-89-3 package, which offers better thermal dissipation. All variants share the same low-quiescent CMOS architecture but are selected based on the specific voltage rail requirements of the downstream digital ICs.
