R1114Q161D-TR-FE

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

The R1114Q161D-TR-FE is a CMOS low-dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It provides a fixed output voltage of 1.6 V with a maximum load current capability of 150 mA. The device operates within an input voltage range of 2 V to 6 V and features a typical power supply rejection ratio (PSRR) of 60 dB. Key electrical parameters include a quiescent current of 75 µA, a line regulation of 0.02 %/V, and a load regulation of 22 mV. The dropout voltage is specified at 220 mV typically, with a maximum of 350 mV. The unit is housed in an SC-82AB-4 package and supports surface-mount installation.

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

Verify the exact output voltage code '16' corresponds to 1.6 V in the official datasheet before ordering. Confirm the SC-82AB-4 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your application's environmental conditions. Check for RoHS compliance documentation if required by your manufacturing standards.

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

Select this component when a fixed 1.6 V output is required with minimal external components. Consider the 150 mA current limit for load demands. Evaluate the 2 V minimum input voltage against your source supply variations. The 60 dB PSRR makes it suitable for noisy environments where ripple suppression is critical.
