Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of

the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the

Electrical Characteristics tables.

Note 2: Min and Max limits are guaranteed by design, test, or statistical analysis. Typical numbers are not guaranteed, but do represent the most likely norm. Due

Note 3: Thermal shutdown will occur if the junction temperature exceeds 150˚C. This function is only active in PWM mode.

Note 4: The LM3202 is designed for mobile phone applications where turn-on after power-up is controlled by the system controller and where requirements for a

small package size overrule increased die size for internal Under Voltage Lock-Out (UVLO) circuitry. Thus, it should be kept in shutdown by holding the EN pin low

until the input voltage exceeds 2.7V.

Note 5: The hysteresis voltage is the minimum voltage swing on FB that causes the internal feedback and control circuitry to turn the internal PFET switch on and

then off, during test mode.
