SGM2052

1.5A, Ultra-High PSRR, Fast Load Transient,

Bias Rail CMOS Voltage Regulator

GENERAL DESCRIPTION

FEATURES

The SGM2052 is an ultra-high PSRR, fast transient

response, low noise and low dropout voltage linear

regulator which is designed using CMOS technology. It

provides 1.5A output current capability. The operating

input voltage range is from 0.5V to 5.5V and bias

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

adjustable output voltage range is from 0.5V to 3.3V.

● Input Supply Voltage Range: 0.5V to 5.5V

● Bias Supply Voltage Range: 2.5V to 5.5V

● Adjustable Output Voltage Range: 0.5V to 3.3V

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

● High PSRR: 70dB (TYP) at 1kHz

● Low Dropout Voltage: 75mV (TYP) at 1.5A

● Low Bias Input Current: 96μA (TYP)

● Very Low Bias Input Current in Shutdown: < 1μA

● Low Noise: 29μV_RMS(TYP)

Other features include logic-controlled shutdown mode,

short-circuit current limit and thermal shutdown

protection. The SGM2052 has automatic discharge

function to quickly discharge V_OUTin the disabled status.

● Fast Load Transient Response

● Output Current Limit

● Stable with Small Case Size Ceramic Capacitors

● Thermal Shutdown Protection

The SGM2052 is available in a Green WLCSP-0.8×1.2-6B-A

package. It operates over an operating temperature

range of -40℃ to +125℃.

● Logic Level Enable Input for ON/OFF Control

● -40℃ to +125℃ Operating Temperature Range

● Available in a Green WLCSP-0.8×1.2-6B-A Package
