All test items listed under ELECTRICAL CHARACTERISTICS are done under the pulse load condition (Tj ≈Ta = 25°C) except
for Ripple Rejection and Output Voltage Temperature Coefficient.
1 The operation of reverse current protection circuit is guaranteed when VOUT ≥ 2.0 V. The reverse current protection
mode is always turned on when VIN = 0 V.
