The amount of the capacitance may be increased without limit. This input capacitor must be located as close as possible to the device to assure input stability and less noise. For PCB layout, a wide copper trace is required for both VIN and GND. The input capacitor should be at least equal to, or greater than, the output capacitor for good load transient performance。 Output Capacitor An output capacitor is required for the stability of the LDO. The recommended output capacitance is from 1μF to 10μF, Equivalent Series Resistance (ESR) is from 5mΩ to 500mΩ, and temperature characteristics are X7R or X5R. Higher capacitance values help to improve load/line transient response. The output capacitance may be increased to keep low undershoot/overshoot. Place output capacitor as close as possible to OUT and GND pins. ON/OFF Input Operation The PJ9500 EN pin is internally held low by a 1-MΩ resistor to GND. The PJ9500 is turned on by setting the EN pin higher than VIH threshold, and is turned off by pulling it lower than VIL threshold. If this feature is not used, the EN pin should be tied to IN pin to keep the regulator output on at all time. Low Quiescent Current Cellular phone baseband internal digital circuits typically operate all the time. That requires LDO stays on at all times. However, in the standby mode, the microprocessor consumes only around 100~300μA. Since the phone stays in standby for the longest percentage of time, using a 0.8μA quiescent current LDO, instead of 100μA, saves 99.2μA and can substantially extends the battery standby time. The PJ9500, consuming only 0.8μA quiescent current, provides great power saving in portable and low power applications. Current Limit Protection When output current at the OUT pin is higher than current limit threshold or the OUT pin is short-circuiting to GND, the current limit protection will be triggered and clamp the output current to a pre-set level to prevent over-current and to protect the regulator from damage due to overheating. Thermal Overload Protection The 9500 has internal thermal protection. When the temperature is too high, such as a short circuit in the output pins or a device with a very large load current and a large voltage drop, the internal thermal protection circuit will be triggered, which will shut down the power supply MOSFET and prevent LDO damage. Once the excessive thermal conditions are eliminated and the temperature of the device drops, the thermal protection circuit will restore control of the power MOSFET and allow the LDO device to enter normal operation www.pingjingsemi.com Revision：1.0 Oct-2023 10 / 16 PJ9500 Series Low Dropout Regulators Package Outline SOT-23 Dimensions in mm www.pingjingsemi.com Revision：1.0 Oct-2023 11 / 16 PJ9500 Series Low Dropout Regulators Package Outline SOT-89 Dimensions in mm www.pingjingsemi.com Revision：1.0 Oct-2023 12 / 16 PJ9500 Series Low Dropout Regulators Package Outline SOT-23-3 Dimensions in mm 1.6 2.8 ±0.1 10 0.127 +0.05/-0.02 ±0.1 ±0.1 2.92 12 R0.15MAX 0.95±0.1 0.35±0.05 R0.15MAX 0.06 12 ± 0.05 0.65 ±0.1 1.1 ±0.1 10 www.pingjingsemi.com Revision：1.0 Oct-2023 13 / 16 PJ9500 Series Low Dropout Regulators Package Outline SOT-23-5 Dimensions in mm 2.92 ±0.1 1.6 2.8 ±0.1 ± 0.1 10 0.127 +0.05/-0.02 1.9±0.1 12 R0.15MAX 0.95 ±0.1 0.35±0.05 R0.15MAX 0.06 12 ± 0.05 0.65 ±0.1 1.1 ±0.1 10 www.pingjingsemi.com Revision：1.0 Oct-2023 14 / 16 PJ9500 Series Low Dropout Regulators Package Outline DFN1x1-4L Dimensions in mm 0.625 BSC 1±0.05 0.25±0.05 1±0.05 05 0. 0. 5± 0. 05 5± 0.
