S-13A1C32-U5T1U3

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

The S-13A1C32-U5T1U3 is a positive voltage regulator from the S-13A1 Series, manufactured by ABLIC Inc. It provides a fixed output voltage of 3.2 V with an accuracy of ±1.0%. The device supports an input voltage range of 1.5 V to 5.5 V and delivers up to 1000 mA of output current. Key electrical parameters include a dropout voltage of 70 mV typ. at 300 mA, current consumption of 60 μA typ. during operation, and ripple rejection of 70 dB typ. at 1.0 kHz. It operates within a temperature range of -40°C to +85°C and utilizes a SOT-89-5 package.

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

Verify the specific ordering suffix U5T1U3 corresponds to the SOT-89-5 package and tape packing format as defined in the manufacturer's product name structure. Confirm that the C type designation matches the requirement for an unavailable discharge shunt function and an available pull-down resistor. Ensure environmental compliance with lead-free (Sn 100%) and halogen-free specifications before procurement.

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

Select this component when a fixed 3.2 V output is required with high accuracy. The C type variant is suitable for designs needing a pull-down resistor but not a discharge shunt function. Ensure input and output capacitors are set to equal values of 2.2 μF or more ceramic capacitors to prevent oscillation. Verify thermal dissipation capabilities if operating near maximum output currents.
