DIODES Incorporated Voltage Regulators - Linear PT7M8202B18TA5EX

The PT7M8202B18TA5EX is a low dropout linear voltage regulator designed for portable RF and wireless applications. It supports an output current of 300mA and operates within a wide input voltage range of 1.8V to 5.5V, with a selectable output voltage range of 1.2V to 3.3V in 100mV steps. The device features ultra-low noise performance, with output noise measured at 30¬µVRMS at 1.2V, making it suitable for sensitive RF applications. Key specifications include a dropout voltage of 270mV at 300mA for a 3.3V output, high ripple rejection of 80dB at 1kHz, and a low standby current of 0.1¬µA. The PT7M8202B18TA5EX also incorporates protection features such as output current-limit and thermal shutdown. It is compatible with low ESR ceramic capacitors and is available in lead-free and green packaging options, including SOT23-5L, SC70-5L, and TDFN-6L. The operating temperature range is from -40¬8C to +85¬8C, making it suitable for various environmental conditions.
