DIODES Incorporated Voltage Regulators - Linear PAM3101CCA330

The PAM3101CCA330 is a linear voltage regulator designed for positive voltage regulation with a maximum output current of 300mA. It features a low dropout voltage of 180mV at 300mA output, making it suitable for battery-powered applications. The device operates within a supply voltage range of 2.5V to 5.5V and has a quiescent current of 65µA, which contributes to its efficiency in portable electronics. This regulator offers high power supply rejection ratio (PSRR) of 70dB at 1kHz, ensuring effective suppression of AC noise on the input power supply. It includes essential protection features such as thermal shutdown, current limiting, and short circuit protection, enhancing reliability under extreme operating conditions. The PAM3101 is stable with an output capacitor of 2.2µF or greater and is available in compact packages like SOT-23, SOT-89, SC70, and DFN1.6x1.6, making it ideal for space-constrained applications. However, it is important to note that this part is not recommended for new designs, with a suggestion to consider the AP2125/2127 series instead.
