Parameter Condition Min Typ Max Units Output Voltage Accuracy IOUT = 100uA -2 -3 2 3 % % Line Regulation VIN = VOUT +1V to 5.5V 0.05 0.2 % Load Regulation IOUT = 0.1mA to 150mA 2 3 % Dropout Voltage IOUT = 50mA IOUT = 150mA 75 210 500 mV mV Quiescent Current VEN < 0.4V 0.2 2 µA Ground Pin Current (Per Regulator) IOUT = 0mA IOUT = 150mA 75 80 120 150 µA µA PSRR (Ripple Rejection) f = 100Hz, CBYP = 0.1µF, ILOAD = 50mA f = 1kHz, CBYP = 0.1µF, ILOAD = 50mA f = 10kHz, CBYP = 0.1µF, ILOAD = 50mA 62 64 64 dB dB dB Current Limit VOUT = 0V 225 mA Output Noise COUT = 1.0µF, CBYP = 0.1µF, f = 10Hz to 100kHz 57 µV (rms) Enable Input (EN1 and EN2) Enable Input Logic Low VIN = 2.7V to 5.5V, regulator shutdown 0.2 V Enable Input Logic High VIN = 2.7V to 5.5V, regulator enabled 1.6 V Enable Input Current VIL < 0.4V, regulator shutdown VIH > 1.6V, regulator enabled 0.01 0.01 µA µA Thermal Shutdown Thermal Shutdown Temperature 150 °C Hysteresis 10 °C Turn-on/Turn-off Characteristics Turn-on Time 40 150 µs Discharge Resistance 500 Ω Notes: 1. Exceeding the absolute maximum rating may damage the device. 2. The device is not guaranteed to function outside its operating rating. 3. The maximum allowable power dissipation of any TA (ambient temperature) is PD(max) = (TJ(max)–TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The θJA of the MIC5264x.xYML (all versions) is 75°C/W on a PC board (see ”Thermal Considerations” section for further details). 4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF. 5. Specification for packaged product only. |
