Description
The R5324D Series is a CMOS-based multi positive voltage regulator IC with high output voltage accuracy, low supply current, low noise, low dropout, and high ripple rejection. It consists of three voltage regulators, each containing a voltage reference unit, an error amplifier, resistors for setting output voltage, a short current limit circuit, and a chip enable circuit. The chip enable function helps prolong battery life. These regulators are suitable for power supply in handheld communication equipment due to their low dropout voltage, excellent load transient response, and line transient response. The ICs are packaged in SON-8, allowing for high-density mounting on boards.Specifications and features
