DIODES Incorporated Voltage Regulators - DC DC Switching Regulators PAM2301CAAB250

The PAM2301CAAB250 is a step-down DC-DC converter designed for efficient power management in portable applications. It operates with an input voltage range of 2.5V to 5.5V and can deliver an output current of up to 800mA. The output voltage is adjustable from 0.6V to the input voltage, with specific versions available for fixed outputs of 3.3V and 1.2V. The device features a power-saving Pulse-Skipping Modulation (PSM) mode, which reduces quiescent current to approximately 40OºA under light load conditions, enhancing battery life. The PAM2301 employs a constant frequency PWM control for stability and transient response, with a switching frequency of 1.5MHz. It includes several protective features such as under-voltage lockout, short circuit protection, and thermal shutdown. The device is housed in a compact TSOT25 package and is compliant with RoHS standards, making it suitable for environmentally conscious designs. This regulator is applicable in various devices, including cellular phones, portable electronics, and battery-powered widgets.
