Not underlined: [[Pb]]/INCLUDES > MCV Underlined: [[G]]/RoHS COMPATIBLE or [[G]]/RoHS [[Pb]] Please contact your TOSHIBA sales representative for details as to environmental matters such as the RoHS compatibility of Product. The RoHS is the Directive 2002/95/EC of the European Parliament and of the Council of 27 January 2003 on the restriction of the use of certain hazardous substances in electrical and electronic equipment. The product(s) in this document (“Product”) contain functions intended to protect the Product from temporary small overloads such as minor short-term overcurrent or overheating. The protective functions do not necessarily protect Product under all circumstances. When incorporating Product into your system, please design the system (1) to avoid such overloads upon the Product, and (2) to shut down or otherwise relieve the Product of such overload conditions immediately upon occurrence. For details, please refer to the notes appearing below in this document and other documents referenced in this document.

Note 3: 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).

Standard Application Circuit CIN 0.33 μF IN OUT TA4800AF GND ADJ R2 R1 COUT 3.3 μF Load • Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND. The use of a monolithic ceramic capacitor (B Characteristic or X7R) of low ESR (equivalent series resistance) is recommended. The IC may oscillate due to external conditions (output current, temperature, or the type of the capacitor used). The type of capacitor required must be determined by the actual application circuit in which the IC is used. Setting Output Voltage • The output voltage is determined by the equation shown below. When you control the output voltage with R1, a recommended value to use for R2 is 5 kΩ. R1 and R2must be placed as close as possible to each other, and the board trace to the ADJ terminal must be kept as short as possible. R1 VOUT = VREF × ( 1 + ) R2 Usage Precautions • The IC might be destroyed if a voltage greater than the input terminal voltage is applied to the output terminal, or if the input terminal is connected to GND during operation. To prevent such an occurrence, connect a diode as in the following diagram. CIN 0.33 μF IN OUT TA4800AF GND ADJ R2 R1 COUT 3.3 μF Load • There is a possibility that internal parasitic devices may be generated when momentary transients cause a terminal’s potential to fall below that of the GND terminal. In such case, that the device could be destroyed. The voltage of each terminal and any state must therefore never fall below the GND potential. • Low voltage Do not apply voltage to the Product that is lower than the minimum operating voltage, or the Product’s protective functions will not operate properly and the Product may be permanently damaged. 5 2009-09-30 TA4800AF • Overcurrent Protection The overcurrent protection circuits in the Product are designed to temporarily protect Product from minor overcurrent of brief duration. When the overcurrent protective function in the Product activates, immediately cease application of overcurrent to Product. Improper usage of Product, such as application of current to Product exceeding the absolute maximum ratings, could cause the overcurrent protection circuit not to operate properly and/or damage Product permanently even before the protection circuit starts to operate. • Overheating Protection The thermal shutdown circuits in the Product are designed to temporarily protect Product from minor overheating of brief duration. When the overheating protective function in the Product activates, immediately correct the overheating situation. Improper usage of Product, such as the application of heat to Product exceeding the absolute maximum ratings, could cause the overheating protection circuit not to operate properly and/or damage Product permanently even before the protection circuit starts to operate. 6 2009-09-30 TA4800AF PDmax – Ta (W) 12 Ta = Tc Condition: Number of IC = 1 Reflow soldering on a ceramic substrate 3.5 VIN = 5.3 V VOUT = 3.3V VOUT – Tj PDmax (V) VOUT 10 3.4 8 Allowable power dissipation I OUT = 5 mA 3.3 100 mA 500 mA 4 50 mm × 50 mm × 0.8 mm 30 mm × 30 mm × 0.8 mm Single Output voltage 80 100 120 140 160 6 3.2 2 0 0 20 40 60 3.1 −50 0 50 100 150 Ambient temperature Ta (°C) Junction temperature Tj (°C) VOUT – VIN 4 20 I B – VIN Tj = 25°C 3 10 mA 2 I B (mA) Quiescent current (V) I OUT = 500 mA 100 mA 15 VOUT Output voltage 10 I OUT = 500 mA 1 VOUT = 3.3V 0 Tj = 25°C 0 2 4 6 8 5 100 mA 10 mA 0 0 2 4 6 8 Input voltage VIN (V) Input voltage VIN (V) I B – Tj 30 VIN = 5.3 V 30 I B – IOUT VIN = 5.3 V Tj = 25°C I B (mA) 20 I OUT = 1 A I B (mA) Quiescent current 100 150 0A 0 50 20 Quiescent current 10 10 0 −50 0 0 200 400 600 800 1000 Junction temperature Tj (°C) Output current I OUT (mA) 7 2009-09-30 TA4800AF VOUT – I OUT 3.5 4 VOUT – I OUT (V) 3.4 (V) VOUT Output voltage VIN = 5.3 V VOUT = 3.3V Tj = 25°C 3 VOUT 3.3 Output voltage 2 3.2 1 VIN = 5.3 V VOUT = 3.3V Tj = 25°C 0 0 0.5 1 1.5 2 2.5 3.1 0 200 400 600 800 1000 Output current I OUT (mA) Output current I OUT (A) VD – I OUT 0.8 VOUT = 3.3V Tj = 25°C 0.8 VD – Tj VOUT = 3.3V Tj = 25°C (V) (V) Tj = −40℃ 0.6 85℃ 25℃ 0.4 125℃ 0.6 I OUT = 1 A VD Dropout voltage Dropout voltage VD 0.4 500 mA 0.2 100 mA 1000 0 −50 0.2 0 0 200 400 600 800 0 50 100 150 Output current I OUT (mA) Junction temperature Tj (°C) I PEAK – Tj 2.5 3.0 I PEAK – VD VOUT = 3.3V I PEAK (A) I PEAK (A) 2.0 2.5 Tj = 25°C 2.0 1.5 Peak output current Peak output current 50 100 1.5 1.0 1.0 0.5 VIN = 5.3 V VOUT = 3.3V 0 -50 0 0.5 150 0 0 5 10 15 20 Junction temperature Tj (°C) Dropout voltage VD (V) 8 2009-09-30 TA4800AF Package Dimensions HSIP5-P-1.27B Unit: mm 1.5±0.2 6.5±0.2 5.2±0.2 0.6max 5.5±0.2 9.5±0.3 1.1±0.2 1.5±0.2 0.6max 0.6±0.1 0.7±0.1 0.7max 0.5±0.1 0.8max 0.5±0.1 2.3±0.2 1.27 Weight: 0.36 g (typ.) 0.1±0.1 9 2009-09-30 TA4800AF RESTRICTIONS ON PRODUCT USE • Toshiba Corporation, and its subsidiaries and affiliates (collectively “TOSHIBA”), reserve the right to make changes to the information in this document, and related hardware, software and systems (collectively “Product”) without notice. • This document and any information herein may not be reproduced without prior written permission from TOSHIBA.
