NATIONAL SEMICONDUCTOR ADDS USER-CONFIGURABLE 500MA LOW-DROPOUT REGULATORS (LDO) TO MICROPOWER FAMILY
- Output Voltage Regulated To +/-0.76% Tolerance
- On-Board Diagnostic Functions for Product Customization
- 5.0V, 3.3V and Adjustable Output Voltages
- 470mV LDO Voltage at Full Load
SANTA CLARA, Calif., August 7, 1995 -- National Semiconductor Corporation, a leading supplier of high-performance, high-precision power management ICs, today expanded its micropower low dropout (LDO) regulator line with the introduction of two new low-power 500mA devices. Developed by National as a product for shaping information, the LP2960 includes standard and user-definable diagnostic functions frequently required for battery management, making them especially attractive for the design of portable equipment. The full array of add-on features includes logic-controlled shutdown, a warning/error flag to indicate an out-of-regulation condition, a low- temperature coefficient reference (1.235V) and an auxiliary comparator.
"With the active building-block approach used in the LP2960 series, system designers have greater latitude to easily modify and differentiate their end products," noted Jim Douglas, National Semiconductor product marketing engineer. "Its greatest appeal is to customers who want or need design flexibility and 'micropower' performance not achievable with a conventional LDO or NPN regulator."
The ICs are also well suited for industrial power-management applications requiring multiple low-voltage power rails, such as converting 5V to 3.3V or tracking regulation on multiple power supplies.
National's regulators offer 5V, 3.3V or adjustable output voltage options. The A-version offers a reference quality output voltage tolerance of +/-0.76% and a standard version rated at +/-1.5% tolerance. Both feature a low 300microAmp quiescent current at shutdown for prolonged battery life, a feature especially desirable for electronic systems in automobiles.
