(GND – 0.3V) to (VDD +0.3)V Maximum Junction Temperature, TJ ...........................+150°C Maximum Power Dissipation......... Internally-Limited (Note 6) Storage Temperature.....................................-65°C to +150°C † 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. DC CHARACTERISTICS Electrical Specifications: Unless otherwise noted, VIN =(VR + 0.5V) or 2.3V, whichever is greater, IOUT =1 mA, CIN =COUT = 4.7 µF (X7R Ceramic), TA =+25°C. Boldface type applies for junction temperatures, TJ (Note 7), of -40°C to +125°C. Parameters Sym. Min. Typ. Max. Units Conditions Input Operating Voltage VIN 2.3 6.0 V Note 1 Input Quiescent Current Iq — 140 220 µA IL =0 mA, VIN =VR +0.5V, VOUT = 0.8V to 5.0V Input Quiescent Current for SHDN Mode ISHDN —0.1 3 µA SHDN =GND Maximum Output Current IOUT 1 —— A VIN = 2.3V to 6.0V (Note 1) Line Regulation VOUT/ (VOUT x VIN) —0.05 0.3 %/V (VR +0.5)V VIN 6V Load Regulation VOUT/VOUT -1.5 ±0.5 1.5 %IOUT = 1 mA to 1A, VIN =(VR + 0.6)V (Note 4) Output Short-Circuit Current IOUT_SC —1.7 — A VIN =(VR + 0.5)V, RLOAD <0.1, Peak Current Adjust Pin Characteristics Adjust Pin Reference Voltage VADJ 0.402 0.410 0.418 VVIN = 2.3V to VIN =6.0V, IOUT =1 mA Adjust Pin Leakage Current IADJ -10 ±0.01 +10 nA VIN =6.0V, VADJ =0V to6V Adjust Temperature Coefficient TCVOUT — 40 — ppm/°C Note 3 Fixed-Output Characteristics Voltage Regulation VOUT VR –2.5% VR ±0.5% VR +2.5% V Note 2 Dropout Characteristics Dropout Voltage VIN –VOUT — 220 500 mV IOUT =1A, VIN(MIN) =2.3V (Note 5) Note 1: The minimum VIN must meet two conditions: VIN 2.3V and VIN VR +2.5% VDROPOUT. 2: VR is the nominal regulator output voltage for the fixed cases. VR = 1.2V, 1.8V, etc. VR is the desired set point output voltage for the adjustable cases. VR =VADJ x((R1/R2) + 1). See Figure 4-1. 3: TCVOUT =(VOUT-HIGH –VOUT-LOW)x 10 6/(VR x Temperature). VOUT-HIGH is the highest voltage measured over the temperature range. VOUT-LOW is the lowest voltage measured over the temperature range. 4: Load regulation is measured at a constant junction temperature using low duty-cycle pulse testing. Load regulation is tested over a load range from 1 mA to the maximum specified output current. 5: Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2% below its nominal value that was measured with an input voltage of VIN =VR +0.5V. 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, JA). Exceeding the maximum allowable power dissipation will cause the device operating junction temperature to exceed the maximum 150°C rating. Sustained junction temperatures above 125°C can impact 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. |
