The TL750M and TL751M series are low-dropout positive voltage regulators specifically designed for battery-powered systems. The TL750M and TL751M series incorporate onboard overvoltage and current-limiting protection circuitry to protect the devices and the regulated system. Both series are fully protected against 60-V load-dump and reverse-battery conditions. Extremely low quiescent current, even during full-load conditions, makes the TL750M and TL751M series ideal for standby power systems. The TL750M and TL751M series offers 5-V, 8-V, 10-V, and 12-V options. The TL751M series has the addition of an enable (ENABLE) input. The ENABLE input gives the designer complete control over power up, allowing sequential power up or emergency shutdown. When ENABLE is high, the regulator output is placed in the high-impedance state. The ENABLE input is TTL- and CMOS-compatible. The TL750MxxC and TL751MxxC are characterized for operation over the virtual junction temperature range 0C to 125C.
