PD/(VIN - VOUT) mA Output Current (Peak).. 300 mA Output Voltage .. (VSS - 0.3V) to (VIN + 0.3V) SHDN Voltage .. (VSS - 0.3V) to +30V † Notice: Stresses above those listed under “Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICSElectrical Specifications: Unless otherwise specified, all limits are established for VIN = VR + 2.0V, Note 1 , COUT = 1 µF (X7R), CIN = 1 µF (X7R), VSHDN = VIN, TA = +25°C ParametersSym.Min.Typ.Max.UnitsConditionsInput / Output Characteristics Input Operating VIN 2.0 — 28.0 V Note 1 Voltage Input Quiescent IQ — IL = 0 mA Current — 50 105 µA 1.8V VOUT 5.0V — 60 115 µA 5.1V VOUT 12.0V — 65 125 µA 12.1V VOUT 18.0V Shutdown Current ISHDN — 0.01 0.10 µA SHDN = 0V Maximum Output IOUT — VIN = VR + 3.0V Current 100 — — mA VOUT < 3.0V 150 — — mA VOUT 3.0V Current Limiter ILIMIT — 200 — mA Output Short Circuit IOUT_SC — 40 — mA Current Output Voltage VOUT VR - 2.0% VR VR + 2.0% V IOUT = 10 mA, Note 2 Regulation VOUT Temperature TCVOUT — ±100 — ppm/°C IOUT = 20 mA, Coefficient -40°C TA 85°C, Note 3Note 1: The minimum VIN must meet one condition: VIN (VR + 2.0V). 2: VR is the nominal regulator output voltage with an input voltage of VIN = VR + 2.0V. For example: VR = 1.8V, 2.5V, 3.0V, 3.3V, etc. 3: TCVOUT = (VOUT-HIGH - VOUT-LOW) * 106 / (VR * Temperature), VOUT-HIGH = highest voltage measured over the temperature range. VOUT-LOW = lowest voltage measured over the temperature range. 4: Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output voltage due to heating effects are determined using thermal regulation specification TCVOUT. 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured value with an applied input voltage of VR + 2.0V. 2009-2013 Microchip Technology Inc.
