DS22008D-page 3 MCP1702 1.0 ELECTRICAL CHARACTERISTICS Absolute Maximum Ratings † VDD...............................................................................+14.5V All inputs and outputs w.r.t. .............(VSS-0.3V) to (VIN+0.3V) Peak Output Current ...................................................500 mA Storage temperature .....................................-65°C to +150°C Maximum Junction Temperature ................................... 150°C ESD protection on all pins (HBM;MM) ............... ≥ 4kV; ≥ 400V † Notice: Stresses above those listed under “Maximum Rat- ings” 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. DC CHARACTERISTICS Electrical Specifications: Unless otherwise specified, all limits are established for V IN = VOUT(MAX) + VDROPOUT(MAX), Note 1, ILOAD = 100 µA, COUT = 1 µF (X7R), CIN = 1 µF (X7R), TA = +25°C. Boldface type applies for junction temperatures, T J of -40°C to +125°C. (Note 7) Parameters Sym Min Typ Max Units Conditions Input / Output Characteristics Input Operating Voltage VIN 2.7 — 13.2 V Note 1 Input Quiescent Current Iq —2.0 5 µA IL = 0 mA Maximum Output Current IOUT_mA 250 —— mA For VR ≥ 2.5V 50 100 — mA For VR < 2.5V, VIN ≥ 2.7V 100 130 — mA For VR < 2.5V, VIN ≥ 2.95V 150 200 — mA For VR < 2.5V, VIN ≥ 3.2V 200 250 — mA For VR < 2.5V, VIN ≥ 3.45V Output Short Circuit Current IOUT_SC —400 — mA VIN = VIN(MIN) (Note 1), VOUT = GND, Current (average current) measured 10 ms after short is applied.

For example: VR = 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.0V, or 5.0V. The input voltage VIN = VOUT(MAX) + VDROPOUT(MAX) or VIN = 2.7V (whichever is greater); IOUT = 100 µA. 3: TCVOUT = (VOUT-HIGH - VOUT-LOW) *10 6 / (V R * ΔTemperature), 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 VOUT(MAX) + VDROPOUT(MAX) or 2.7V, whichever is greater. 6: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, θJA). Exceeding the maximum allowable power dissipation will cause the device operating junction temperature to exceed the maximum 150°C rating. Sustained junction temperatures above 150°C can impact the device reliability. 7: The junction temperature is approximated by soaking the device under test at an ambient temperature equal to the desired Junction temperature. The test time is small enough such that the rise in the Junction temperature over the ambient temperature is not significant. |
