TC1301A-DDAVUATR

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

The TC1301A-DDAVUATR is a dual-output Low Dropout (LDO) regulator integrated with a microcontroller reset monitor function, manufactured by Microchip Technology. It features two independent regulators: VOUT1 provides up to 300 mA and VOUT2 provides up to 150 mA. The device operates within an input voltage range of 2.7V to 6.0V. Key electrical parameters include a typical dropout voltage of 104 mV at 300 mA for VOUT1 and 150 mV at 150 mA for VOUT2. Quiescent current consumption is typically 116 µA when both outputs are active. The RESET function monitors the VDET pin with a threshold range of 2.20V to 3.20V and includes a typical delay of 300 ms.

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

Verify the specific suffix DDAVUATR against the official Microchip datasheet to confirm exact output voltage combinations and package type. Ensure compatibility with required ceramic output capacitance values for stability. Confirm operating temperature range requirements align with the specified -40°C to +125°C junction temperature limits before finalizing procurement.

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

Select this component when a compact solution combining dual LDOs and system reset monitoring is required. Consider the TC1301A variant if independent voltage detection via the VDET pin is necessary, as opposed to the internally connected VOUT1 monitoring found in the TC1301B. Evaluate thermal resistance requirements based on the chosen package option to ensure adequate heat dissipation under maximum load conditions.
