ST1S12xx  
Synchronous rectification with enable, 0.7 A, 1.7 MHz fixed or  
adjustable step-down switching regulator in TSOT23-5L  
Features  
Step-down current mode PWM (1.7 MHz) DC-  
DC converter  
3% DC output voltage tolerance  
Synchronous rectification  
Fixed output voltage 1.2 V, 1.8 V, and ADJ  
(available on request 1.5 V, 2.5 V and 3.3 V)  
TSOT23-5L  
Enable function  
Internal soft start  
Typical efficiency: > 90%  
0.7 A output current capability  
required. Moreover, a low output ripple is  
guaranteed by the current mode PWM topology  
and by the use of low ESR SMD ceramic  
capacitors. The device is thermally protected and  
the current is limited to prevent damage due to  
accidental short-circuit. The ST1S12Gxx is  
available in the TSOT23-5L package.  
Not switching quiescent current: max 600 µA  
over temperature range  
R  
typ. 250 mΩ and 400 mΩ  
DSON  
Uses tiny capacitors and inductors  
Operative junction temp. -40°C to 125°C  
Available in TSOT23-5L package  
Description  
The ST1S12Gxx is a step down DC-DC converter  
optimized for powering low-voltage digital cores in  
HDD applications and, generally, to replace the  
high current linear solution when the power  
dissipation may cause high heating of the  
application environment. It provides up to 0.7 A  
over an input voltage range of 2.5 V to 5.5 V. A  
high switching frequency (1.7 MHz) allows the  
use of tiny surface-mount components. In addition  
to the resistor divider to set the output voltage  
value, only an inductor and two capacitors are  
Table 1.
