PMIC - Voltage Regulators - Linear

PT7M8216B09XZEX is a linear voltage regulator integrated circuit, designed by Princeton Technology Corporation. This is a low dropout (LDO) three-terminal regulator and PT7M8216B09XZEX consists of a driver, high voltage MOSFET, a voltage reference and a current limiter.

Application Field

PT7M8216B09XZEX is mainly used in automotive and industrial applications such as large mobile phone, LCD TV, laptop, PoE applications, amplifier and surge currents protection. This kind of LDO can provide better protection against transient noises, which is suitable for those applications with big highest ripple current and wide operating temperature range.

Working Principle

The internal MOSFET of PT7M8216B09XZEX can provide low RDS(on) and low on-resistance, which can pass higher current and produce less heat. The built-in voltage reference can provide more precise output voltage regulation and current accurate with higher accuracy and faster transient response. Besides, the current limiter can avoid output short circuit current and malfunction, protect other IC or components under the output.

Conclusion

The PT7M8216B09XZEX is a kind of integrated low dropout (LDO) three-terminal linear voltage regulator. It is mainly used in automotive, industrial and PoE applications due to its low RDS(on), high voltage reference and current limiter circuitry. On the other hand, its noise immunity can also protect other IC or components against any surge currents or transient noises.
