NCP134AMX120TCG Description

Short technical summary and product information.

The NCP134AMX120TCG is a positive fixed output linear voltage regulator from On Semiconductor, designed to deliver a stable 1.2V output at up to 500mA. It operates with an input voltage range of 0.8V to 5.5V and requires a bias voltage of 2.4V to 5.5V. The device achieves an ultra-low dropout voltage of 150mV maximum at 500mA load, making it suitable for low headroom applications.

 

Key electrical characteristics include a typical quiescent current of 80µA, dropping to 0.5µA in disable mode, which helps extend battery life in portable devices. The regulator offers high accuracy of ±1.5% over temperature and 0.5% at 25°C. It provides a minimum PSRR of 80dB at 1kHz for effective noise rejection. Protection features include over current, over temperature, and under voltage lockout (UVLO), with an enable control feature for power management.

 

The device is housed in a 4-XDFN exposed pad package (1.2x1.2mm) for surface mount assembly. It is rated for an operating temperature range of -40°C to 85°C and has a maximum junction temperature of 150°C. ESD protection is rated at 2000V HBM and 200V MM.
