TPS7H1101A-SP (正在供货)

TPS7H1101A-SP 1.5-V to 7-V Input, 3-A, Radiation-Hardened LDO Regulator



The TPS7H1101A-SP is an improved version of the TPS7H1101-SP allowing the use of the enable feature across the entire input voltage range. It is a radiation-hardened LDO linear regulator that uses a PMOS pass element configuration. It operates over a wide range of input voltage, from 1.5 V to 7 V while offering excellent PSRR. The TPS7H1101A-SP features a precise and programmable foldback current limit implementation with a very-wide adjustment range. To support the complex power requirements of FPGAs, DSPs, or microcontrollers, the TPS7H1101A-SP provides enable on and off functionality, programmable soft start, current sharing capability, and a Power Good open-drain output.
