AiT Semiconductor Inc. www.ait-ic.com A6140 CMOS LOW DROPOUT VOL TAGE REGULATOR (LDO) 36V , 150mA, LOW POWER CONSUMPTION REV2.0 - OCT 2013 RELEASED, JUL 2021 UPDATED - - 1 - DESCRIPTION FEATURES The A6140 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 150mA of current while consuming only 2μA of quiescent current (typical). The input operating range is specified from 2.5V to 36V, making it an ideal choice for multi-cell battery systems, two to six primary cell battery -powered applications, 9V Alkaline and one or two cell li -Ion- powered applications , bus voltage power supply systems and other high DC voltage systems. The wide input voltage can make it well wi thstand the impact of surge voltage and ensure the stability of output voltage. Only 2uA (typical) at light load can reduce the standby power consumption of the whole system, which is high benefit in multi-battery power supply systems. The A6140 is available in SOT-23 and SOT89-3 packages.

AiT Semiconductor Inc. www.ait-ic.com A6140 CMOS LOW DROPOUT VOL TAGE REGULATOR (LDO) 36V , 150mA, LOW POWER CONSUMPTION REV2.0 - OCT 2013 RELEASED, JUL 2021 UPDATED - - 9 - DETAILED INFORMATION Overview The A6140 low-dropout regulators (LDO) consumes only 2 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. Applications Note: 1. The phase compensation circuit and ESR of the output capacitor are used inside the circuit to compensate, so a capacitor larger than 1.0uF must be connected to the ground. 2. It is recommended to use 1uF polar capacitors for input and output, and to keep the capacitors as close to the VIN and VOUT pins of LDO as possible. 3. Pay attention to the use conditions of input and output voltages and load currents to avoid the power consumption (PD) inside the IC exceeding the maximum power consumption allowed by the package. PD=(VIN－VOUT)×IOUT TPN = PD×RθJA+T TPN is junction temperature T is ambient temperature. 4. When the input voltage V IN 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. If VIN lower than 2.5V, the VOUT is: VOUT = VIN - VDropout
