371 / 398 page ![]() M261/M262/M263 Mar 25, 2020 Page 371 of 398 Rev 1.02 8.5 Analog Electrical Characteristics 8.5.1 LDO Symbol Parameter Min Typ Max Unit Test Condition VDD DC Power Supply 1.7 - 3.6 V VLDO Output Voltage - 1.26 - V Turbo mode - 1.20 - V Normal run mode - 0.96 - V Low leakage power-down mode - 0.86 - V Ultra low leakage Power- down mode TA Temperature -40 - 105 ℃ Note: 1. It is recommended a 0.1μF bypass capacitor is connected between VDD and the closest VSS pin of the device. 2. For ensuring power stability, a 2.2μF Capacitor must be connected between LDO_CAP pin and the closest VSS pin of the device. 3. For ensuring power stability, a 2.2μF Capacitor must be connected between LDO_CAP pin and the closest VSS pin of the device. 8.5.2 DC-DC Typical values are at VDD = 3.3V, TA = 25°C, Vsw is connected to 4.7uH inductance and LDO_CAP is connected to 2.2uF capacitance unless otherwise specified. Symbol Parameter Min Typ Max Unit Test Condition VIN Input Voltage Range 1.7 - 3.6 V VOUT Output Voltage Range 1.2 1.26 1.4 V 1.15 1.20 1.33 V IOUT_MAX Maximum DC Output Current - - 30 mA VIN>1.7V IQ_DCDC Quiescent Current - - 15 uA No load, normal mode, only buck regulator VLINE Line Regulation -5 - 5 % IOUT=30mA, VIN=1.7V to 3.6V VLOAD Load Regulation -5 - 5 % IOUT=0.2mA to 30mA PEFF Power Efficiency - 80 - % IOUT= 2~30mA LOUT = 4.7uH, DCR ≤ 180mΩ Note: 1. It is recommended a 2.2μF and 0.1μF bypass capacitor is connected between VDD and the closest VSS pin of the device. 2. For ensuring power stability, a 2.2μF Capacitor must be connected between LDO_CAP pin and the closest VSS pin of the device. |
