S-13R1B16-A4T2U3

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

The S-13R1B16-A4T2U3 is a CMOS positive voltage regulator with a fixed 1.6 V output, housed in an HSNT-4 (1010) package. It supports an input voltage range of 2.0 V to 5.5 V and delivers up to 150 mA output current. Key electrical parameters include ±1.0% output voltage accuracy, a typical dropout voltage of 0.58 V at 100 mA, and a ripple rejection ratio of 70 dB at 1.0 kHz. The device operates within a temperature range of -40°C to +85°C.

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

• Integrated reverse current protection function limits reverse flow from the output to the input pin without requiring external diodes.
• Built-in overcurrent protection circuit safeguards the load against excessive current and short circuits.
• Thermal shutdown circuit prevents damage by stopping regulation when junction temperature exceeds safe limits.
• ON/OFF control logic allows for active high operation to manage power consumption.

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

Verify the specific ordering suffix A4T2U3 corresponds to the HSNT-4 (1010) package and tape reel packing configuration. Confirm that the B-type designation matches the required discharge shunt availability and pull-down function settings for your circuit design. Ensure compatibility with the specified ceramic capacitor requirements for stable operation.

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

Select this component when a fixed 1.6 V output is required with low quiescent current consumption. Consider the B-type variant specifically if the discharge shunt function is needed but the constant current source pull-down is not desired. Evaluate thermal dissipation capabilities based on the HSNT-4 package constraints under maximum load conditions.

S-13R1A16-A4T2U3: Same output voltage and package; differs in discharge shunt and pull-down function availability.

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

What is the maximum reverse current allowed?

The reverse current protection function limits the reverse current flowing from the VOUT pin to the VIN pin to a maximum of 0.09 μA.

How does the ON/OFF pin behave in the B-type variant?

In the S-13R1 Series B type, the ON/OFF pin is active high. Unlike the A-type, it does not have an internal constant current source pull-down, so it should not be left floating.
