Note 2: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

The capacitances should be determined experimentally. In particular, adequate investigation should be made so that there is no problem even in high or low temperatures. 4 2006-11-02 TA48015F PDmax – Ta CONDITION: NUMBER OF IC = 1 REFLOW SOLDERING ON A CERAMIC SUBSTRATE Ta = Tc 10 PDmax – S 10 Allowable power dissipation PDmax (W) Allowable power dissipation PDmax (W) 12 8 6 4 50 × 50 × 0.8 mmt 2 30 × 30 × 0.8 mmt SINGLE 0 0 20 40 60 80 120 100 140 SUBSTRATE SIZE ：50×50×1.6mmt SUBSTRATE QUALITY ：GLASS EPOXY CUPPER BASE THICKNESS ：35μm 5 3 1 10 160 Ambient temperature Ta (°C) 100 1000 Cupper Base Area Size S VOUT – Tj 10000 2 (mm ) VOUT – VIN 1.575 2 IOUT = 5 mA 1.55 Output voltage VOUT (V) Output voltage VOUT (V) VIN = 3.5 V 1.525 1.5 1.475 1.5 IOUT = 10 mA 1 0.1 A 0.5 A 0.5 1.45 Tj = 25°C 1.425 −50 0 50 100 Junction temperature Tj 0 0 150 2 (°C) 4 Input voltage IB – VIN VIN (V) IB – Tj 10 20 VIN = 3.5 V IB (mA) 8 6 Quiescent current Quiescent current IB (mA) Tj = 25°C IOUT = 0.5 A 4 IOUT = 0.1 A 2 16 12 IOUT = 1 A 8 4 IOUT = 0 A IOUT = 10 mA 0 0 6 2 Input voltage 4 0 −50 6 VIN (V) 0 50 Junction temperature Tj 5 100 150 (°C) 2006-11-02 TA48015F IB – IOUT VD – Tj 1 VIN = 3.5 V Tj = 25°C (V) 16 Dropout voltage VD Quiescent current IB (mA) 20 12 8 4 0 0 0.2 0.4 0.6 Output current IOUT 0.8 0.8 0.6 IOUT = 0.5 A IOUT = 0.1 A 0.4 0.2 0 -50 1 IOUT = 1 A (A) 0 50 Junction temperature Tj VIN = 3.5 V Tj = 25°C (°C) VIN = 3.5 V IOUT = 50mA Tj = 25°C 1.5 1.0 0.5 (dB) 70 60 Ripple rejection R.R.
