XC62E_1

XC62E Series Boosting Voltage Regulators ETR0311_002 ■GENERAL DESCRIPTION The XC62E series are a group of positive output voltage regulators that can supply up to 1A of output current using an external transistor. Low power and high accuracy are achieved through CMOS process and laser trimming technologies. The series consists of a high precision voltage reference, an error correction circuit and a short-circuit protected output driver. In stand-by mode, supply current can be dramatically cut. Since the input-output voltage differential is small, loss control efficiency is good. The XC62E is particularly suited for use with battery operated portable products, and products where supply current regulation is required. The series are available in an ultra small SOT-25 package. In connection with the CE function, apart from the negative logic XC62EP series, a positive logic XC62ER series (custom) is also available. ■APPLICATIONS ●Portable cameras and video recorders ●Battery powered equipment ●Palmtops ●Reference voltage sources ■FEATURES Dropout Voltage : 0.1A@100mA (Performance depends on the external transistor characteristics.)

CE Vss CIN: 10μF (Tantalum) CL: 47μF (Tantalum) 10μF minimum ■OPERATIONAL EXPLANATION Output voltage (VOUT) can be fixed by revising the external transistor's base current. This can be done by comparing the detected voltage level and the setting voltage power supply level. With the XC62EP (CE negative voltage), if a voltage above the CE pin's "H" level is applied, the IC will enter stand-by mode where the base and differential amplifier's currents are regulated. ■NOTES ON USE 1. PNP Transistor The selection of a transistor should take into account output current, input voltage and power dissipation for each specific application. It is recommended that a transistor that has a low output saturated voltage (VCE) and high hFE characteristics be used. 2. RB Resistor Although the IC unit is protected by a base current remitter circuit, it is recommended that a resistor (RB) be connected between the transistor's base and the IC's EXT pin to protect the transistor. Required output current can be calculated using the following equation although characteristic variations and conditions of use should be carefully checked before use. The following equation also indicates the conditions needed to obtain IOUT (MAX.) at VIN (MIN.). However, the larger the input current, the larger the output current (IOUT) that can be obtained. VIN (MIN.)-1.2(V) RB 0.7(V) RBE IOUT (MAX.) hFE 3. RBE Resistor, CL Capacitor To prevent oscillation due to output load variation, use of a phase compensation capacitor CL is recommended. Please use a Tantalum capacitor of at least 10mF. Please also use an RBE resistor of less than 47kΩ. An RBE resistor of between 20kΩ and 47kΩ is recommended for less power consumption. 4. Input Impedance In order to control oscillation brought about as a result of impedance at the power supply line, connect a capacitor of 10μF or more (Tantalum) between the external transistor's emitter and the ground pin. ●Protection Circuit The built-in protection circuit is to protect the IC only. Therefore to prevent output shorts and overshoot current through the transistor, use of a resistor RB or an overshoot current protection circuit is recommended. Care should also be taken with the transistor's power dissipation. 6/12 XC62E Series ■TYPICAL PERFORMANCE CHARACTERISTICS 7/12 XC62E Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) CL=10μF (tantalum) CL=10μF (tantalum) CL=10μF (tantalum) Output Current:IOUT (mA) Output Current: IOUT (mA) Output Current: IOUT (mA) Input Voltage: VIN (V) Input Voltage: VIN (V) Input Voltage: VIN (V) VIN=6V IOUT=100mA, CL=10μF (tantalum) VIN=5V IOUT=100mA, CL=10μF (tantalum) VIN=4.3V IOUT=100mA, CL=10μF (tantalum) Ambient Temperature: Topr (℃) Ambient Temperature: Topr (℃) Ambient Temperature: Topr (℃) VIN=6V VIN=5V VIN=4.3V Ambient Temperature: Topr (℃) Ambient Temperature: Topr (℃) Ambient Temperature: Topr (℃) 8/12 XC62E Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (7) Input Transient Response 9/12 XC62E Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (8) Load Transient Response (9) Ripple Rejection Rate 10/12 XC62E Series ■PACKAGING INFORMATION ●SOT-25 ■MARKING RULE ●SOT-25 5 ① ② ①Not used 4 ③④ ②Represents integer of output voltage MARK (XC62ER Type) 2 3 4 5 6 VOLTAGE (V) 2.x 3.x 4.x 5.x 6.x MARK (XC62EP Type) 2 3 4 5 6 VOLTAGE (V) 2.x 3.x 4.x 5.x 6.x 1 2 3 ③Represents decimal number of output voltage MARK (XC62ER Type) 0 1 2 3 4 5 6 7 8 9 VOLTAGE (V) x.0 x.1 x.2 x.3 x.4 x.5 x.6 x.7 x.8 x.9 MARK (XC62EP Type) 0 1 2 3 4 5 6 7 8 9 VOLTAGE (V) x.0 x.1 x.2 x.3 x.4 x.5 x.6 x.7 x.8 x.9 ④Based on internal standards 11/12 XC62E Series 1.
