CMOS LDO Regulators for Portable Devices 1ch 150mA CMOS LDO Regulators No.11020EAT10 BHSA3WGUT Series Description The BHSA3WGUT Series are 150 mA output CMOS regulators that deliver a highly stable output voltage with the precision of 1%. With the use of ROHMs original technology, the load regulation of only 2 mV, 100 mV I/O drop voltage, and the load transient of 50mV (at 1mA100mA) have been achieved. The VCSP60N1 package is extremely compact as just 0.96 mm 0.96 mm, and the IC s enhanced protection circuits contribute to improved application safety. Features 1) High accuracy output voltage: 1% 2) I/O drop voltage: 100 mV (at 100 mA) 3) Load Transient Vout : 50mV (at 1mA100mA) 4) Stable with ceramic capacitors (1F) 5) Low bias current: 40 A 6) High ripple rejection ratio: 63 dB (Typ., 1 kHz) 7) Output voltage on/off control 8) Built-in overcurrent (short) and thermal shutdown circuits 9) Uses the VCSP60N1 WL-CSP package. Applications Battery-driven portable devices, etc. Product Line 150 mA BHSA3WGUT Series Product name 1.8 2.8 3.0 Package BHSA3WGUT VCSP60N1 Model name: BHSA3W a b Description Symbol Output voltage specification Output voltage (V) 18 1.8 V (Typ.) a 28 2.8 V (Typ.) 30 3.0 V (Typ.) b Package GUT: VCSP60N1 www.rohm.com 2012.02 - Rev.A 1/14 2012 ROHM Co., Ltd.
