The ADP3333ARMZ-3.3-R7 is a precision low dropout (LDO) voltage regulator from Analog Devices, part of the ADP333x family. It operates with an input voltage range of 2.6V to 12V and delivers a load current up to 300mA, with a fixed 3.3V output.
This regulator boasts high accuracy of ±0.8% at 25°C and ±1.8% over temperature, line, and load variations. Its ultralow dropout voltage is typically 140mV at 300mA, and it requires only a 1.0µF output capacitor for stability, being insensitive to ESR and compatible with various capacitor types, including MLCCs.
Key features include ultralow quiescent current (70µA typical) and a low shutdown current (<1µA). It also incorporates current and thermal limiting for protection. The device is housed in an ultrasmall 8-lead MSOP package, making it suitable for space-constrained applications.
Applications for the ADP3333ARMZ-3.3-R7 include cellular phones, PCMCIA cards, personal digital assistants (PDAs), and DSP/ASIC power supplies where stable and efficient voltage regulation is critical.
