NOT RECOMMENDED FOR NEW DESIGN  
SC1452  
Dual 150mA LDO Regulator  
with Programmable Reset  
POWER MANAGEMENT  
Features  
Description  
The SC1452 is a state of the art device intended to  
provide maximum performance and flexibility in battery  
operated systems. It has been designed specifically to  
fully support a single Li-Ion battery and its external charger  
voltages.  
‹ Up to 150mA per regulator output  
‹ Low quiescent current (130µA typical with both  
outputs at 150mA)  
‹ Low dropout voltage  
‹ Wide selection of output voltages  
‹ Stable operation with ceramic caps  
‹ Tight load and line regulation  
‹ Current and thermal limiting  
‹ Reverse input polarity protection  
‹ <1µA off-mode rrent  
The SC1452 contains two independently enabled, ultra  
low dropout voltage regulators (ULDOs). It operates from  
an input voltage range of 2.25V to 6.5V, and a wide  
variety of output voltage options are available which are  
designed to provide an initial tolerance of ±1% and ±2%  
over temperature.  
‹ Logic controlled able  
‹ Active low reets valid for VIN down to 0V  
‹ Programle reset  
‹ Full industrial tempeature range  
‹ 10-Pin MSOP package. Also available in Lead-free,  
fuly WEEE and RoHS compliant  
Each regulator has an associated active-low reset signal  
which is asserted when the voltage output declines  
below the preset threshold. Once the output recovers,  
the reset continues to be asserted (delayed) for a  
predetermined time, 50ms for reset A and 150ms for  
reset B. In the case of regulator B, the delay time may be  
reduced by the addition of an external capacitor.  
Applications  
‹ Cellular telephones  
‹ Ptop/Laptop computers  
‹ Battery-powered equipment  
‹ Bar code scanners  
‹ SMPS post regulator/dc to dc modules  
‹ High efficiency linear power supplies  
‹ DSP supplies  
The SC1452 has a bypass pin to enable the usto  
capacitively decouple the bandgap reference for very low  
output noise (down to 50µVrms).  
The devices utilize CMOS technology to achieve very low  
operating currents (typically 130uA with both  
outputs supplying 150mA). he dropouoltage is  
typically 155mV at 150mA, ing to olong battery  
life. In addition, the devices are guarad to provide  
400mA of peak current for applications which require  
high initial inrush current. They have been designed to  
be used with low ESR ceramic capacitors to save cost  
and PCB area.  
The SC1452 comes in the low profile 10-lead MSOP  
package.
