General Description
The XL2596 is a 150 KHz fixed frequency
PWM buck (step-down) DC/DC converter,
capable of driving a 3A load with high
efficiency, low ripple and excellent line and
load regulation. Requiring a minimum
number of external components, the regulator
is simple to use and include internal
frequency compensation and a
fixed-frequency oscillator.
The PWM control circuit is able to adjust the
duty ratio linearly from 0 to 100%. An enable
function, an over current protection function
is built inside. When second current limit
function happens, the operation frequency
will be reduced from 150KHz to 50KHz. An
internal compensation block is built in to
minimize external component count.

高品质5A大电流低压差稳压IC UZ1084
信息内容：1,UTC公司高品质大电流LDO。2，TO-263封装常备现货，可直接用支付宝下单。 5A ADJUSTABLE/FIXED LOW DROPOUT LINEAR REGULATOR DESCRIPTION The UTC UZ1084-ADJ/Fixed voltages are low dropout three-terminal regulators with 5A output current capability. These devices have been optimized for low voltage applications including VTT bus termination, where transient response and minimum input voltage are critical. On-chip thermal limiting provides protection against any combination of overload and ambient temperature that would create excessive junction temperatures. FEATURES *Fast transient response *Low dropout Voltage at up to 5A *Load regulation : 0.5% typical *On-chip thermal limiting APPLICATIONS *Desktop PCs, RISC and embedded processors’ supply *GTI, SSTL logic reference bus supply *Low voltage VCC logic supply *Battery-powered circuitry *Post regulator for switching supply *Cable and ADSL modems’ DSP core supply *Set Top Boxes and Web Boxes modules’ supply
