ELECTRICAL CHARACTERISTICS

Absolute Maximum Ratings †

Supply Input Voltage (VIN) ............................................................................................. ...................................0V to +7V

Enable Input Voltage (VEN) ............................................................................................... ................................0V to +7V

Power Dissipation (PD) ............................................................................................................Internally Limited (Note 1)

ESD Rating (Note 2) ......................................................................................... ........................................................ 2 kV

Operating Ratings ‡

Input Voltage (VIN) .................................................................................................... .................................. +2.7V to +6V

Enable Input Voltage (VEN) .................................................................................................................................0V to VIN

† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at those or any other conditions above those indicated

in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability.

‡ Notice: The device is not guaranteed to function outside its operating ratings.

Note 1: The maximum allowable power dissipation of any TA (ambient temperature) is PD(MAX) = (TJ(MAX) – TA)/θJA.

Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the reg-

ulator will go into thermal shutdown. The θJA of the MIC5252-x.xYM5 (all versions) is 235°C/W on a PC

board. See

Section 4.7 “Thermal Considerations” for further details.

2: Devices are ESD sensitive. Handling precautions recommended.
