CMOS LDO Regulators for Portable Equipments 1ch 150mA CMOS LDO Regulators No.11020ECT03 BHRB1WGUT series Description The BHRB1WGUT series is a line of 150 mA output CMOS regulators that deliver a highly stable precision ( 1%) output voltage. Proprietary ROHM technology enables a small load regulation of 2 mV and a dropout voltage of 100 mV. At just 1.0 mm 1.04 mm, the new VCSP60N1 package is extremely compact, and the IC s enhanced protection circuits contribute to improved end products characteristics. Features 1) High accuracy output voltage: 1% 2) Dropout voltage: 100 mV (at 100 mA) 3) Stable with ceramic capacitors 4) Low bias current: 34 A 5) High ripple rejection ratio: 63 dB (Typ., 1 kHz) 6) Output voltage on/off control 7) Built-in overcurrent and thermal shutdown circuits 8) VCSP60N1 WL-CSP package : (1.01.040.6mm) Applications Battery-driven portable devices, etc. Product line 150 mA BHRB1WGUT Series Product name 1.5 1.8 2.5 2.8 2.9 3.0 3.1 3.3 Package BHRB1WGUT VCSP60N1 Model name: BHRB1W a b Symbol Description Output voltage specification Output voltage (V) Output voltage (V) 15 1.5 V (Typ.) 29 2.9 V (Typ.) a 18 1.8 V (Typ.) 30 3.0 V (Typ.) 25 2.5 V (Typ.) 31 3.1 V (Typ.) 28 2.8 V (Typ.) 33 3.3 V (Typ.) b Package GUT: VCSP60N1 www.rohm.com 2011.01 - Rev.C 1/8 2011 ROHM Co., Ltd.
