AiT Semiconductor Inc. www.ait-ic.com A6154 CMOS LOW DROPOUT REGULATOR (LDO) 36V , 150mA, ULTRALOW POWER CONSUMPTION REV1.0 - APR 2020 RELEASED - - 9 - DETAILED INFORMATION Overview The A6154 low-dropout regulators (LDO) consumes only 2.5 μA of quiescent current at light load and delivers excellent line and load transient performance. These characteristics, combined with low noise and good PSRR with low dropout voltage, make this device ideal for portable consumer applications. Thermal Considerations When the junction temperature is too high, the thermal protection circuitry sends a signal to the control logic that will shut down the IC. The IC will restart when the temperature has sufficiently cooled down. The maximum power dissipation is dependent on the thermal resistance of the case and the circuit board, the temperature difference between the die junction and the ambient air, and the rate of air flow. The GND pin must be connected to the ground plane for proper dissipation. Operation with VIN Lower Than 2.5V The device normally operates with input voltages above 2.5V. At input voltages below the 2.5V, the device does not operate. Operation with VIN Larger Than 2.5V When VIN is greater than 2.5V, if V IN is also higher than the output set value plus the device dropout voltage, VOUT is equal to the set value. Otherwise, VOUT is equal to VIN minus the dropout voltage.
