SH323 ¢« SH223 « SH123 FAIRCHILD eee 5A,3V A Schlumberger Company Voltage Regulator Hybrid Products Description Connection Diagram The SH232 is a hybrid regulator with §.0 V fixed output —-2-Pin Metal Package and 3.0 A output capability. It has the inherent characteristics of the monolithic 3-terminal regulators, i.e., full thermal overload, short circuit and safe area protection. All devices are packaged in hermetically ineut + sealed TO-3s providing 50 W power dissipation. If the “ safe operating area is exceeded, the device shuts Le ( down rather than failing or damaging other system — x components (Note 1). This feature eliminates costly 7 output circuitry and overly conservative heat sinks th iy 3 typical of high-current regulators built from ek Te! discrete components. \\ 7 5 = 3.0 A OUTPUT CURRENT ( ” INTERNAL CURRENT AND THERMAL ‘ 2 OVERLOAD PROTECTION / ; = INTERNAL SHORT CIRCUIT PROTECTION ™ LOW DROPOUT VOLTAGE (TYPICALLY 2.0 V ourpUT 2 COMMON 3 @ 3.0 A) = 50 W POWER DISSIPATION STEEL T0-3 PACKAGE = ALL PIN-FOR-PIN COMPATIBLE WITH THE (Top View) LM323, $6323 Order Intormation Type Package Code Part No. sH323 Metal GN SH323SC $H223 Metal GN SH223SV SH123 Metal GN SH123SM Block Diagram Va — ON SHUTDOWN is = incur REGULATOR lennon aM, SHORT Rsc 2 circurr PROTECTION yh | Vout COMMON ee a

Of uF COMMON Design Considerations The device is designed to operated without external This device has thermal overload protection from compensation components. However, the amount of excessive power and internal short circuit protection external filtering of this voltage regulator depends which limits the circuit's maximum current. Thus, the upon the circuit layout. If in a specific application the device is protected from overload abnormalities. regulator is more than four inches from the filter Although the internal power dissipation is limited, the capacitor, a 1 uF solid tantalum capacitor should be junction temperature must be kept below the maximum used at the input. A 0.1 uF capacitor should be used specified temperature (150°C). It is recommended by at the output to reduce transients created by fast the manufacturer that the maximum junction switching loads, as seen in the basic test circuit. temperature be kept as low as possible for increased These filter capacitors must be located as close to reliability. To calculate the maximum junction the regulator as possible. temperature or heat sink required, the following thermal resistance values should be used. Caution: Permanent damage can result from forcing the output voltage higher than the input voltage. A eee protection diode from output to input should be used if Package Typ Max this condition exists.
