TC1185-3.3VCT713

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

The TC1185-3.3VCT713 is a fixed-output 3.3V low dropout regulator from the TC1185 series, manufactured by Microchip Technology. It provides a maximum output current of 150 mA with an input voltage range of 2.7 V to 6.0 V. The device features a typical supply current of 50 µA and includes power-saving shutdown mode reducing current to 0.5 µA max. It incorporates overcurrent and overtemperature protection, operates within -40°C to +125°C, and utilizes a 5-pin SOT-23 package.

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

Verify the specific suffix '713' against official Microchip documentation to confirm tape and reel packaging details. Ensure the ordering code matches the required temperature grade and output voltage tolerance. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

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

Select this component for applications requiring low ground current to extend battery life in portable devices. The 150 mA output capability suits moderate load requirements. Consider the shutdown feature if system power management requires remote control of the regulator state. Verify that the input voltage remains above the dropout threshold under all operating conditions.

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

This part belongs to the TC1014/TC1015/TC1185 family of CMOS LDOs. The TC1185 variant specifically offers 150 mA output, distinguishing it from the 50 mA TC1014 and 100 mA TC1015. All variants share similar features including low dropout voltage, shutdown capability, and the 5-pin SOT-23 package format.
