Boldface specifications apply over the TA range of -40°C to +85°C. Parameters Sym. Min. Typ. Max. Units Conditions Temperature Ranges Operating Junction Temperature Range TJ -40 — +125 °C Steady state Storage Temperature Range TA -65 — +150 °C Maximum Junction Temperature TJ — — +150 °C Transient Package Thermal Resistance Thermal Resistance, 6LD-SOT-23 JA — 190.5 — °C/W Thermal Resistance, 8LD-2x3 DFN JA —75 — °C/W DC CHARACTERISTICS (CONTINUED) Electrical Characteristics: Unless otherwise indicated, VIN = 1.2V, COUT = CIN = 10 µF, L = 4.7 µH, VOUT =3.3V, IOUT =15 mA, TA = +25°C. Boldface specifications apply over the TA range of -40°C to +85°C. Parameters Sym. Min. Typ. Max. Units Conditions Note 1: 3.3 k resistive load, 3.3V OUT (1 mA). 2: For VIN > VOUT, VOUT will not remain in regulation. 3: IQ is measured from VOUT; VIN quiescent current will vary with boost ratio. VIN quiescent current can be estimated by: (IQPFM * (VOUT/VIN)), (IQPWM * (VOUT/VIN)). 4: Peak current limit determined by characterization, not production tested 5: 220 resistive load, 3.3V OUT (15 mA). |
