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. Output Capacitor An output capacitor is required for the stability of the LDO. The recommended output capacitance is 10μF, ceramic capacitor is recommended, 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 VOUT and GND pins. Dropout Voltage The dropout voltage refers to the voltage difference between the VIN and VOUT pins while operating at specific output current. The dropout voltage VDROP also can be expressed as the voltage drop on the pass-FET at specific output current (IRATED) while the pass-FET is fully operating at ohmic region and the pass-FET can be characterized asan resistance RDS(ON). Thus the dropout voltage can bedefined as (VDROP = VIN − VOUT = RDS(ON) x IRATED). Fornormal operation, the suggested LDO operating range is (VIN > VOUT + VDROP) for good transient response and PSRR ability. Vice versa, while operating at the ohmic region will degrade the performance severely. Thermal Application For continuous operation, do not exceed the absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated as below: TA=25°C, PCB, The max PD= (125°C − 25°C) / (Thermal Resistance °C/W) Power dissipation (PD) is equal to the product of the output current and the voltage drop across the output pass element, as shown in the equation below: PD = (VIN – VOUT) × IOUT Ver1.2 7 Aug 3,2021 HE2280 series 80V 150mA Low Power LDO Packaging Information SOT23-3L Ver1.2 8 Aug 3,2021 HE2280 series 80V 150mA Low Power LDO 3-pin SOT89 Outline Dimensions Ver1.2 9 Aug 3,2021
