SG78xxA/78xx ® TM Positive Fixed Voltage Regulator P RODUCT D ATASHEET KEY FEATURES DESCRIPTION All protective features of thermal shutdown, current limiting, and safe-area control have been designed into these units and since these regulators require only a small output capacitor for satisfactory performance, ease of application is assured. Although designed as fixed-voltage regulators, the output voltage can be increased through the use of a simple voltage divider. The low quiescent drain current of the device insures good regulation when this method is used. Product is available in hermetically sealed TO-257 (both case grounded ‘G’ and isolated ‘IG’), TO-3, TO-39 and LCC packages. IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com Output Voltage Set Internally to ±1.5% on SG78xxA Input Voltage Range to 50V max. on SG78xxA Two Volt Input-Output Differential Excellent Line and Load Regulation Foldback Current Limiting Thermal Overload Protection Voltages Available: 5V, 12V, 15V Contact Factory for Other Voltage Options Available in Surface Mount Package HIGH RELIABILITY FEATURES - SG78xxA/78xx WWW . Microsemi .C OM The SG78xxA/SG78xx series of positive regulators offer self contained, fixed-voltage capability with up to 1.5A of load current and input voltage up to 50V (SG78xxA series only). These units feature a unique on-chip trimming system to set the output voltages to within ±1.5% of nominal on the SG78xxA series, ±2.0% on the SG78xx series. The SG78xxA versions also offer much improved line and load regulation characteristics. Utilizing an improved bandgap reference design, problems have been eliminated that are normally associated with the Zener diode references, such as drift in output voltage and large changes in the line and load regulation.

All voltages are with respect to Ground. Currents are positive into, negative out of specified terminal. WWW . Microsemi .C OM Device Output Voltage Note 3: Operation at high input voltages is dependent upon load current. When load current is less than 5mA, output will rise out of regulation as inputoutput differential increases beyond 30V. Note also from figure 1, that maximum load current is reduced at high voltages. The 50V input rating of the SG78xxA series refers to ability to withstand high line or transient conditions without damage. Since the regulator’s maximum current capability is reduced, the output may fall out of regulation at high input voltages under nominal loading.
