Dual Low-Dropout Linear Regulators  
with RESET or Low-Noise Output in UCSP or QFN  
General Description  
Features  
The MAX8530/MAX8531 offer the benefits of low-  
dropout voltage and ultra-low power regulation in  
subminiaturized UCSP and QFN packages with an inte-  
grated microprocessor reset circuit (MAX8530 only).  
The devices operate from a 2.5V to 6.5V input and  
deliver up to 200mA and 150mA outputs with low  
dropout of 100mV (typ) at 100mA. Designed with an  
internal P-channel MOSFET pass transistor, the supply  
current is kept at a low 130µA (with both LDOs on),  
independent of the load current and dropout voltage.  
Other features include short-circuit protection and  
thermal-shutdown protection.  
Guaranteed 200mA Output Current for OUT1  
Guaranteed 150mA Output Current for OUT2  
Low 100mV (typ) Dropout at 100mA Load for  
both LDOs  
Open-Drain, Active-Low 100ms (min) Reset Timer  
(MAX8530)  
Low 40µV  
Output Noise (MAX8531)  
RMS  
Low 130µA Operating Supply Current  
<1µA Shutdown Current  
The MAX8530 provides microprocessor open-drain,  
active-low reset output to monitor OUT1, eliminating  
external components and adjustments. The MAX8530  
asserts a 100ms (min) RESET signal when OUT1 drops  
below 87% of the nominal output voltage. The MAX8531  
includes a reference bypass pin for low output noise

Both devices include a logic-controlled shutdown input  
and are available in 6-bump UCSP and 6-pin thin QFN  
exposed pad packages.
