AP7333-28SRG-7

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

The AP7333-28SRG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 2.8V output with a maximum continuous load current of 300mA. The device operates within an input voltage range of 2V to 6V and maintains a typical quiescent current of 65µA across the full load spectrum. It features a typical power supply rejection ratio (PSRR) of 65dB at 100Hz and achieves fast transient response with a start-up time of approximately 80µs. The component is housed in a SOT23R-3 surface-mount package.
