Diodes’ AP7372 low-dropout (LDO) regulator affords excessive energy provide ripple rejection (PSRR) and low output noise for precision sign chains. It powers ADCs, DACs, VCOs, and PLLs, serving to meet stringent ripple and noise targets in take a look at and measurement, communication, industrial automation, and medical purposes.
The AP7372 maintains simply 8 µVRMS output noise, impartial of fastened output voltage, and delivers PSRR of 90 dB at 10 kHz, 70 dB at 100 kHz, and 52 dB at 1 MHz. Working from 2.7 V to twenty V, it supplies as much as 200 mA of output present with a typical 120-mV dropout voltage at 200 mA The extensive enter vary covers frequent rails (19.5 V, 12 V, 5 V) and single-cell Li-ion sources, whereas outputs from 1.2 V to five.0 V go well with analog and mixed-signal masses.
4 fixed-output voltages can be found—1.8 V, 2.5 V, 3.3 V, and 5.0 V—together with an adjustable output all the way down to 1.2 V. A devoted resistor-divider pin permits high-quality changes above the nominal fixed-output values. The LDO additionally supplies an allow pin for system-level management, similar to power-up sequencing or shutdown when the regulator is unused. Shutdown present is roughly 3 µA, with a quiescent present of 66 µA.
The AP7372 LDO regulator prices $0.30 every in 1000-piece portions.
