| AS2930 150 mA Low Dropout Voltage Regulator FEATURES * Output Current in Excess of 150mA * 3V, 3.3V, 3.5V, 4.0V, 4.5V & 5.0V Versions Available * Very Low Quiescent Current * Input-Output Differential Less than 0.6V * 60V Load Dump Protection * -50V Reverse Transient Protection * Internal Thermal Overload Protection * Reverse Battery Protection * Short Circuit Protection * Available in TO-220, TO-92, SO-8, SOT-89 Packages * Similar to Industry Standard LM2930 APPLICATIONS * Cordless Telephones * Portable Consumer Equipment * Portable Instrumentation * Radio Control Systems PRODUCT DESCRIPTION The AS2930 is a positive Low Power Voltage Regulator. This device is an excellent choice for use in battery-powered applications, such as cordless telephones, radio control systems, and automotive apllications. The AS2930 was originally designed for automotive applications, all circuitry is protected from reverse battery installations. During line transients, such as a load dump (+60V) when the input voltage to the regulator exceed its maximum operating voltage, this device will automatically shut down to protect both internal circuits as well as the load. The AS2930 is offered as a 3.0V, 3.3V, 3.5V, 4.5V, 5.0V fixed output in 3-pin SOT-89, TO-92/TO-220 packages compatible with other 5V regulators and TO-220/TO-92. The AS2930 is also offered in 5V SO-8 package. ORDERING INFORMATION TO-92 3-PIN AS2930N-X SO-8 AS2930S-X AS2930CS-X SOT-89 3-PIN AS2930M1-X TO-220 AS2930U-X AS2930CU-X Oper. Temp. Range IND. IND.
