S-1335B23-N4T1U3

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

The S-1335B23-N4T1U3 is a CMOS positive voltage regulator from the S-1335 Series, providing a fixed output of 2.3 V with a maximum current capacity of 150 mA. It operates within an input voltage range of 1.5 V to 5.5 V and features a typical dropout voltage of 70 mV at 100 mA. The device includes a built-in soft-start circuit with a fixed time of 0.1 ms typ., overcurrent protection, and an ON/OFF control pin. It consumes 36 μA during operation and 0.1 μA in power-off mode. Ripple rejection is typically 70 dB at 10 kHz. The unit is housed in an SC-82AB package.

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

Verify the specific ordering suffix N4T1U3 corresponds to the SC-82AB tape packaging and lead-free/halogen-free compliance. Confirm that the B-type designation matches the required functional configuration regarding discharge shunt availability and pull-down resistor status for your circuit design. Ensure input and output capacitor values meet the minimum 1.0 μF ceramic requirement for stability.

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

Select this component when a fixed 2.3 V output is required with high accuracy and low quiescent current. The B-type variant is suitable if the discharge shunt function is needed but the pull-down resistor is not desired. Consider the SC-82AB package dimensions for board space constraints. Verify thermal dissipation capabilities if operating near the maximum current limit or ambient temperature extremes.

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

This part belongs to the ABLIC S-1335 Series, a family of 5.5 V input, 150 mA LDO regulators. The series utilizes CMOS technology to achieve low power consumption and high ripple rejection. Variants are distinguished by product type letters (A-M) defining internal logic and protection features, and package codes such as N4T1 for SC-82AB or M5T1 for SOT-23-5.
