Equivalent Circuit Block Diagram Test Circuit (Common to L88MS00T Series) Notes: 1. Because the output capacitor COUT is set at over 100 µF to prevent oscillation at low temperatures, a capacitor that exhibits little change in capacity with temperature variations should be used (such as a tantalum capacitor). 2. Adding capacitor Cn enables external noise suppression and ripple rejection to be improved. However, attention should be given to system stability (phase margin). 3. To ensure operational stability, CIN,C OUT , and Cn should be placed as close to the IC as possible. 4. When the strobe (STB) pin is open, output is turned on by internal bias. When the strobe function is not used, the STB pin should be connected to GND to complete strobe operation. 5. When VIN is minus (–) and GND is plus (+) (reversed connection), excessive current flow will occur.

Function Table On/off Control Input Equivalent Circuit Sample Application Circuit Adjustment of output voltage VOUT (1) Reducing VOUT V OUT can be lowered by externally connecting a resistor R A between the Cn and VOUT pins. (2) Increasing VOUT V OUT can be raised by externally connecting a resistor RB between the Cn and GND pins. The allowable power dissipation is 1.0 W (Ta = 25°C) with no fin attached, but when mounted on a hybrid IC board or printed circuit board, high allowable power dissipation is achieved, despite the compact package. The graph below depicts the relationship between the copper-clad area and allowable power dissipation when mounted on a glass epoxy board (50× 50 × 0.8 tmm 3) with a copper thickness of 18 µm.
