LMS1587CSX-3.3/NOPB Texas Instruments 低压差稳压器

FEATURES DESCRIPTION

The LMS1585A and LMS1587 are low dropout

234• Fast Transient Response

positive regulators with output load current of 5A and

• Available in Adjustable, 1.5V, and 3.3V 3A respectively. Their low dropout voltage (1.2V) and

versions fast transient response make them an excellent

• Current Limiting and Thermal Protection solution for low voltage microprocessor applications.

• Commercial Temp. Tange: 0°C to 125°C The LMS1585A/87 are available in adjustable

• Industrial Temp. Range: −40°C to 125°C versions, which can set the output voltage with only

two external resistors. In addition, they are also • Line Regulation 0.005% (typical)

available in 1.5V and 3.3V fixed voltage versions(1)

.

• Load Regulation 0.05% (typical)

The LMS1585A/87 circuits include a zener trimmed • Direct Replacement for LT® 1585A/87 bandgap reference, current limiting and thermal

shutdown. The LMS1585A/87 series are available in APPLICATIONS KTT (TO-263) and NDE (TO-220) packages.
