The P-channel pass transistor receives data from the error amplifier, over-current protection, output short protection, and thermal protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current and Thermal shutdown circuits become active when the junction temperature exceeds 150℃, or the current exceeds 300mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120℃. The CM2836/B/C switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. ENABLE The Enable pin normally floats high. When actively, pulled low, the PMOS pass transistor shut off, and all internal circuits are powered down. In this state, the quiescent current is less than 2μA. This pin behaves much like an electronic switch. EXTERNAL CAPACITOR The CM2836/B/C is stable with a Low ESR output capacitor to ground of 1.0μF or greater. It can keep stable even with higher ESR capacitors. A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should be larger than 1μF to have a beneficial effect. All capacitors should be placed in close proximity to the pins. A “quiet” ground termination is desirable. 2009/07/17 Rev1.3 Champion Microelectronic Corporation Page 5 CM2836/B/C 300mA LOW ESR CMOS LDO WITH ENABLE TYPICAL CHARACTERISTICS 2009/07/17 Rev1.3 Champion Microelectronic Corporation Page 6 CM2836/B/C 300mA LOW ESR CMOS LDO WITH ENABLE 2009/07/17 Rev1.3 Champion Microelectronic Corporation Page 7 CM2836/B/C 300mA LOW ESR CMOS LDO WITH ENABLE PACKAGE DIMENSION SOT-23-3 (M23) D 3 b1 With Plating c c1 A A1 E1 E A2 b b Base Metal b1 c Section B-B c1 D E 1 2 e E1 b e1 L L1 e θ1 e1 θ θ1 θ A2 A θ2 θ2 A1 L L1 See Section B-B SOT-23-5 (M25) D 5 4 b1 With Plating c c1 A A1 E1 E A2 b b Base Metal b1 c Section B-B c1 D E 1 e 2 3 e1 E1 b L L1 e θ1 e1 θ θ1 θ A2 A θ2 θ2 A1 L 2009/07/17 Rev1.3 See Section B-B L1 Champion Microelectronic Corporation Page 8 CM2836/B/C 300mA LOW ESR CMOS LDO WITH ENABLE SOT-89 (M89) D D1 A L 5° H E φ1.0 e C e1 A 8° L b b1 C D D1 H E e1 b b1 b e SC70-5 2009/07/17 Rev1.3 Champion Microelectronic Corporation Page 9 CM2836/B/C 300mA LOW ESR CMOS LDO WITH ENABLE NUMBERING SCHEME Ordering Number: CM2836/B/Cxyz (note1) Ordering Number: CM2836/B/CG(X)xyz (note2) note1: CM2836/B/C: 300mA CMOS LDO with enable x : Suffix for voltage output (note 3) y : Suffix for Temperature Range (note 4) z : Suffix for Package Type (note 5) note2: CM2836/B/C: 300mA CMOS LDO with enable G : Suffix for Pb Free Product X : Suffix for Halogen Free and PB Free Product note 3: see CMOS LDO Voltage Suffix Table CMOS LDO Voltage Suffix Table Output Voltage Suffix Output Voltage Suffix 1.2V AC 2.5V K 1.5V A 2.6V L 1.7V C 2.7V M 1.8V D 2.8V N 2.0V F 3.0V P 2.1V G 3.1V Q 2.2V H 3.3V S 2.3V I 3.6V V note 4: y= I : -40℃~+85℃ (only I grade support for all CMOS LDOs) note 5: Z is single alphabet with or without digits M25 : SOT-23-5 (TR only) M23 : SOT-23 (TR only) M89 : SOT-89 (TR only) SC70-5 (TR only) 2009/07/17 Rev1.3 Champion Microelectronic Corporation Page 10 CM2836/B/C 300mA LOW ESR CMOS LDO WITH ENABLE IMPORTANT NOTICE Champion Microelectronic Corporation (CMC) reserves the right to make changes to its products or to discontinue any integrated circuit product or service without notice, and advises its customers to obtain the latest version of relevant information to verify, before placing orders, that the information being relied on is current.
