1 / 10 page  LM2941/LM2941C 1A Low Dropout Adjustable Regulator General Description The LM2941 positive voltage regulator features the ability to source 1A of output current with a typical dropout voltage of 0.5V and a maximum of 1V over the entire temperature range. Furthermore, a quiescent current reduction circuit has been included which reduces the ground pin current when the differential between the input voltage and the output volt- age exceeds approximately 3V. The quiescent current with 1A of output current and an input-output differential of 5V is therefore only 30 mA. Higher quiescent currents only exist when the regulator is in the dropout mode (V IN −VOUT ≤ 3V). Designed also for vehicular applications, the LM2941 and all regulated circuitry are protected from reverse battery instal- lations or two-battery jumps. During line transients, such as load dump when the input voltage can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both the internal circuits and the load. Familiar regulator features such as short circuit and thermal overload protection are also provided. Features n Output voltage adjustable from 5V to 20V n Dropout voltage typically 0.5V @ IO = 1A n Output current in excess of 1A n Trimmed reference voltage n Reverse battery protection n Internal short circuit current limit n Mirror image insertion protection n P + Product Enhancement tested n TTL, CMOS compatible ON/OFF switch Connection Diagram and Ordering Information TO-220 Plastic Package DS008823-2 Front View Order Number LM2941T or LM2941CT See NS Package Number TO5A TO-263 Surface-Mount Package DS008823-8 DS008823-9 Order Number LM2941S or LM2941CS See NS Package Number TS5B 16-Lead Ceramic Dual-in-Line Package DS008823-31 Top View Order Number LM2941J/883 5962-9166701QEA See NS Package Number J16A 16-Lead Ceramic Surface Mount Package DS008823-32 Front View Order Number LM2941WG/883 5962-9166701QYA See NS Package Number WG16A June 1999 © 1999 National Semiconductor Corporation DS008823 www.national.com |
