LD59150 Low Dropout (LDO) Linear Regulator
LD59150 Low Dropout (LDO) Linear Regulator
STMicro's LD59150 LDO linear regulator features Power-Good and adjustable startup time for automotive applications
STMicro's LD59150 is a 1.5 A LDO regulator designed for use in various environments. The NMOS topology allows RDS(ON) of the pass element to be reduced, which results in a very small dropout voltage even with very low input supply voltage. Output voltage can be adjusted from 0.8 V to 3.6 V by means of an external resistor divider. The programmable soft-start circuit offers the possibility to control the inrush current at startup providing a monotonic supply voltage to the load. The LD59150 has an enable pin to turn on/off (EN) the regulator and Power Good to monitor the regulated output voltage (PG). A combination of both can be used to set the desired power sequence in case of multiple regulated rails. The LD59150 embeds protection functions, such as current limit and thermal shutdown.
Features
- Ultra-low dropout (65 mV @ 1.5 A) increases power efficiency and reduces power dissipation
- High VOUT accuracy (0.5% typ) provides a clean and precise supply voltage to sensitive loads
- Programmable soft-start reduces inrush current and allows tight control of power sequencing
- Available in DFN10 3 mm x 3 mm package with wettable flanks; a compact package solution with maximum reliability
- Automotive AEC-Q100 Grade 1 qualified
- Power Good function allows power sequencing
- Adjustable output voltage gives design flexibility
- Dual supply pin permits ultra-low dropout operation on very low voltage rails
Applications
- Automotive and industrial post regulation
- Generic POL
- Automotive and industrial ASICs and FPGA supply
- Telecom infrastructure
- Advanced driver-assistance systems (ADAS)
