NCP114BMX120TCG

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

The NCP114BMX120TCG is a 300 mA CMOS Low Dropout (LDO) linear regulator manufactured by onsemi. It provides a fixed 1.2 V output voltage with ±1% accuracy at room temperature. The device operates within an input voltage range of 1.7 V to 5.5 V and features a typical quiescent current of 50 µA. It delivers high power supply ripple rejection of 75 dB at 1 kHz and includes thermal shutdown and current limit protections. The component is housed in a UDFN-4 package (CASE 517CU1) and is designed for stability with ceramic output capacitors.

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

Verify the specific ordering suffix 'MX' corresponds to the UDFN-4 package configuration required for your design. Confirm that the 'B' series designation aligns with your need for a version without the active output discharge function. Ensure compatibility with the specified Pb-Free manufacturing process and check for any recent lifecycle notifications regarding availability or obsolescence status before finalizing procurement plans.

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

Select this component when a fixed 1.2 V rail is required from a single-cell lithium-ion or similar power source. The low dropout characteristic allows operation even when the input voltage is close to the output level. Consider the UDFN-4 package for space-constrained PCB layouts. Verify that the load transient requirements are met by the internal compensation and external capacitor selection, specifically ensuring the use of X5R or X7R dielectric ceramics for optimal performance.

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

This part belongs to the NCP114 family of 300 mA LDO regulators from onsemi. The family offers various fixed voltage options ranging from 0.75 V to 3.6 V. The 'BMX' variant specifically denotes the 1.2 V output option packaged in the compact UDFN-4 form factor. This series is engineered to balance high performance with low power consumption for portable electronics.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same family include NCP114AMX120TCG, which shares identical electrical characteristics but includes an active output discharge function. Other voltage variants such as NCP114BMX180TCG or NCP114BMX300TCG share the same package and pinout but provide different fixed output voltages.
