SGM2037

500mA, Low Noise, Very Low Dropout

Bias Rail CMOS Voltage Regulator

GENERAL DESCRIPTION

FEATURES

The SGM2037 is a low noise, low dropout voltage

linear regulator which is designed using CMOS

technology. It provides 500mA output current capability.

The operating input voltage range is from 0.8V to 5.5V

and bias supply voltage range is from 2.5V to 5.5V. The

output voltage range is from 0.8V to 3.6V.

● 500mA Nominal Output Current

● Input Voltage Range: 0.8V to 5.5V

● Bias Voltage Range: 2.5V to 5.5V

● Fixed Output Voltages: 0.8V, 0.9V, 1.0V, 1.05V,

1.1V, 1.15V, 1.2V, 1.25V, 1.3V, 1.5V, 1.8V, 2.5V, 2.8V,

3.0V, 3.3V, and 3.6V

● Adjustable Output Voltage Range: 0.8V to 3.6V

● Output Voltage Accuracy: ±0.8% at +25℃

● Low Dropout Voltage: 120mV (TYP) at 500mA

● Very Low Bias Input Current: 37μA (TYP)

● Very Low Bias Input Current in Shutdown:

0.01μA (TYP)

Other features include logic-controlled shutdown mode,

short-circuit current limit and thermal shutdown

protection. The SGM2037 has automatic discharge

function to quickly discharge V_OUTin the disabled status.

The SGM2037 is suitable for applications which need

low noise, fast transient response and low I_Q

consumption, such as battery-powered equipment and

smartphones, etc.

● Low Noise: 25μV_RMS(TYP)

● Over-Current and Over-Temperature Protections

● Fast Load Transient Response

● Logic Level Enable Input for ON/OFF Control

● -40℃ to +125℃ Operating Temperature Range

● Available in Green SOT-23-5, SOT-23-6 and

UTDFN-1.2×1.2-6L Packages

The SGM2037 is available in Green SOT-23-5, SOT-23-6

and UTDFN-1.2×1.2-6L packages. It operates over an

ambient temperature range of -40℃ to +125℃.
